+ * Architecture-specific ACPICA Subsystem Data Types
+ *
+ * The goal of these types is to provide source code portability across
+ * 16-bit, 32-bit, and 64-bit targets.
+ *
+ * 1) The following types are of fixed size for all targets (16/32/64):
+ *
+ * BOOLEAN      Logical boolean
+ *
+ * UINT8        8-bit  (1 byte) unsigned value
+ * UINT16       16-bit (2 byte) unsigned value
+ * UINT32       32-bit (4 byte) unsigned value
+ * UINT64       64-bit (8 byte) unsigned value
+ *
+ * INT16        16-bit (2 byte) signed value
+ * INT32        32-bit (4 byte) signed value
+ * INT64        64-bit (8 byte) signed value
+ *
+ * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
+ * compiler-dependent header(s) and were introduced because there is no common
+ * 64-bit integer type across the various compilation models, as shown in
+ * the table below.
+ *
+ * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
+ * char      8    8     8     8     8    8
+ * short     16   16    16    16    16   16
+ * _int32         32
+ * int       32   64    32    32    16   16
+ * long      64   64    32    32    32   32
+ * long long            64    64
+ * pointer   64   64    64    32    32   32
+ *
+ * Note: ILP64 and LP32 are currently not supported.
+ *
+ *
+ * 2) These types represent the native word size of the target mode of the
+ * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
+ * usually used for memory allocation, efficient loop counters, and array
+ * indexes. The types are similar to the size_t type in the C library and are
+ * required because there is no C type that consistently represents the native
+ * data width. ACPI_SIZE is needed because there is no guarantee that a
+ * kernel-level C library is present.
+ *
+ * ACPI_SIZE        16/32/64-bit unsigned value
+ * ACPI_NATIVE_INT  16/32/64-bit signed value

+/* Comment by Rik:
+ *
+ * For some background on GF(2^128) see for example: http://-
+ * csrc.nist.gov/CryptoToolkit/modes/proposedmodes/gcm/gcm-revised-spec.pdf
+ *
+ * The elements of GF(2^128) := GF(2)[X]/(X^128-X^7-X^2-X^1-1) can
+ * be mapped to computer memory in a variety of ways. Let's examine
+ * three common cases.
+ *
+ * Take a look at the 16 binary octets below in memory order. The msb's
+ * are left and the lsb's are right. char b[16] is an array and b[0] is
+ * the first octet.
+ *
+ * 80000000 00000000 00000000 00000000 .... 00000000 00000000 00000000
+ *   b[0]     b[1]     b[2]     b[3]          b[13]    b[14]    b[15]
+ *
+ * Every bit is a coefficient of some power of X. We can store the bits
+ * in every byte in little-endian order and the bytes themselves also in
+ * little endian order. I will call this lle (little-little-endian).
+ * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks
+ * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }.
+ * This format was originally implemented in gf128mul and is used
+ * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length).
+ *
+ * Another convention says: store the bits in bigendian order and the
+ * bytes also. This is bbe (big-big-endian). Now the buffer above
+ * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111,
+ * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe
+ * is partly implemented.
+ *
+ * Both of the above formats are easy to implement on big-endian
+ * machines.
+ *
+ * EME (which is patent encumbered) uses the ble format (bits are stored
+ * in big endian order and the bytes in little endian). The above buffer
+ * represents X^7 in this case and the primitive polynomial is b[0] = 0x87.
+ *
+ * The common machine word-size is smaller than 128 bits, so to make
+ * an efficient implementation we must split into machine word sizes.
+ * This file uses one 32bit for the moment. Machine endianness comes into
+ * play. The lle format in relation to machine endianness is discussed
+ * below by the original author of gf128mul Dr Brian Gladman.
+ *
+ * Let's look at the bbe and ble format on a little endian machine.
+ *
+ * bbe on a little endian machine u32 x[4]:
+ *
+ *  MS            x[0]           LS  MS            x[1]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  103..96 111.104 119.112 127.120  71...64 79...72 87...80 95...88
+ *
+ *  MS            x[2]           LS  MS            x[3]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  39...32 47...40 55...48 63...56  07...00 15...08 23...16 31...24
+ *
+ * ble on a little endian machine
+ *
+ *  MS            x[0]           LS  MS            x[1]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  31...24 23...16 15...08 07...00  63...56 55...48 47...40 39...32
+ *
+ *  MS            x[2]           LS  MS            x[3]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  95...88 87...80 79...72 71...64  127.120 199.112 111.104 103..96
+ *
+ * Multiplications in GF(2^128) are mostly bit-shifts, so you see why
+ * ble (and lbe also) are easier to implement on a little-endian
+ * machine than on a big-endian machine. The converse holds for bbe
+ * and lle.
+ *
+ * Note: to have good alignment, it seems to me that it is sufficient
+ * to keep elements of GF(2^128) in type u64[2]. On 32-bit wordsize
+ * machines this will automatically aligned to wordsize and on a 64-bit
+ * machine also.
+ */
+/*	Multiply a GF128 field element by x. Field elements are held in arrays
+    of bytes in which field bits 8n..8n + 7 are held in byte[n], with lower
+    indexed bits placed in the more numerically significant bit positions
+    within bytes.
+
+    On little endian machines the bit indexes translate into the bit
+    positions within four 32-bit words in the following way
+
+    MS            x[0]           LS  MS            x[1]		  LS

+ * Locks a buffer object for validation. (Or prevents other processes from

+ * a number of measures to prevent deadlocks.
+ *
+ * Deadlocks may occur when two processes try to reserve multiple buffers in
+ * different order, either by will or as a result of a buffer being evicted
+ * to make room for a buffer already reserved. (Buffers are reserved before
+ * they are evicted). The following algorithm prevents such deadlocks from
+ * occuring:
+ * 1) Buffers are reserved with the lru spinlock held. Upon successful
+ * reservation they are removed from the lru list. This stops a reserved buffer
+ * from being evicted. However the lru spinlock is released between the time
+ * a buffer is selected for eviction and the time it is reserved.
+ * Therefore a check is made when a buffer is reserved for eviction, that it
+ * is still the first buffer in the lru list, before it is removed from the
+ * list. @check_lru == 1 forces this check. If it fails, the function returns
+ * -EINVAL, and the caller should then choose a new buffer to evict and repeat
+ * the procedure.
+ * 2) Processes attempting to reserve multiple buffers other than for eviction,
+ * (typically execbuf), should first obtain a unique 32-bit
+ * validation sequence number,
+ * and call this function with @use_sequence == 1 and @sequence == the unique
+ * sequence number. If upon call of this function, the buffer object is already
+ * reserved, the validation sequence is checked against the validation
+ * sequence of the process currently reserving the buffer,
+ * and if the current validation sequence is greater than that of the process
+ * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps
+ * waiting for the buffer to become unreserved, after which it retries
+ * reserving.
+ * The caller should, when receiving an -EAGAIN error
+ * release all its buffer reservations, wait for @bo to become unreserved, and
+ * then rerun the validation with the same validation sequence. This procedure
+ * will always guarantee that the process with the lowest validation sequence
+ * will eventually succeed, preventing both deadlocks and starvation.
+ *
+ * Returns:
+ * -EAGAIN: The reservation may cause a deadlock.
+ * Release all buffer reservations, wait for @bo to become unreserved and

+ * ki_retry	-	iocb forward progress callback
+ * @kiocb:	The kiocb struct to advance by performing an operation.
+ *
+ * This callback is called when the AIO core wants a given AIO operation
+ * to make forward progress.  The kiocb argument describes the operation
+ * that is to be performed.  As the operation proceeds, perhaps partially,
+ * ki_retry is expected to update the kiocb with progress made.  Typically
+ * ki_retry is set in the AIO core and it itself calls file_operations
+ * helpers.
+ *
+ * ki_retry's return value determines when the AIO operation is completed
+ * and an event is generated in the AIO event ring.  Except the special
+ * return values described below, the value that is returned from ki_retry
+ * is transferred directly into the completion ring as the operation's
+ * resulting status.  Once this has happened ki_retry *MUST NOT* reference
+ * the kiocb pointer again.
+ *
+ * If ki_retry returns -EIOCBQUEUED it has made a promise that aio_complete()
+ * will be called on the kiocb pointer in the future.  The AIO core will
+ * not ask the method again -- ki_retry must ensure forward progress.
+ * aio_complete() must be called once and only once in the future, multiple
+ * calls may result in undefined behaviour.
+ *
+ * If ki_retry returns -EIOCBRETRY it has made a promise that kick_iocb()
+ * will be called on the kiocb pointer in the future.  This may happen
+ * through generic helpers that associate kiocb->ki_wait with a wait
+ * queue head that ki_retry uses via current->io_wait.  It can also happen
+ * with custom tracking and manual calls to kick_iocb(), though that is
+ * discouraged.  In either case, kick_iocb() must be called once and only
+ * once.  ki_retry must ensure forward progress, the AIO core will wait
+ * indefinitely for kick_iocb() to be called.

+/*******************************************************
+ * As of Linux 2.1.x, all Linux CD-ROM application programs will use this 
+ * (and only this) include file.  It is my hope to provide Linux with
+ * a uniform interface between software accessing CD-ROMs and the various 
+ * device drivers that actually talk to the drives.  There may still be
+ * 23 different kinds of strange CD-ROM drives, but at least there will 
+ * now be one, and only one, Linux CD-ROM interface.
+ *
+ * Additionally, as of Linux 2.1.x, all Linux application programs 
+ * should use the O_NONBLOCK option when opening a CD-ROM device 
+ * for subsequent ioctl commands.  This allows for neat system errors 
+ * like "No medium found" or "Wrong medium type" upon attempting to 
+ * mount or play an empty slot, mount an audio disc, or play a data disc.
+ * Generally, changing an application program to support O_NONBLOCK
+ * is as easy as the following:
+ *       -    drive = open("/dev/cdrom", O_RDONLY);
+ *       +    drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
+ * It is worth the small change.
+ *
+ *  Patches for many common CD programs (provided by David A. van Leeuwen)
+ *  can be found at:  ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
+ *

+ * accomplish this.  Maybe someday we will get a more targeted error code,

+/**
+ * cnt32_to_63 - Expand a 32-bit counter to a 63-bit counter
+ * @cnt_lo: The low part of the counter
+ *
+ * Many hardware clock counters are only 32 bits wide and therefore have
+ * a relatively short period making wrap-arounds rather frequent.  This
+ * is a problem when implementing sched_clock() for example, where a 64-bit
+ * non-wrapping monotonic value is expected to be returned.
+ *
+ * To overcome that limitation, let's extend a 32-bit counter to 63 bits
+ * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
+ * by the hardware while bits 32 to 62 are stored in memory.  The top bit in
+ * memory is used to synchronize with the hardware clock half-period.  When
+ * the top bit of both counters (hardware and in memory) differ then the
+ * memory is updated with a new value, incrementing it when the hardware
+ * counter wraps around.
+ *
+ * Because a word store in memory is atomic then the incremented value will
+ * always be in synch with the top bit indicating to any potential concurrent
+ * reader if the value in memory is up to date or not with regards to the
+ * needed increment.  And any race in updating the value in memory is harmless
+ * as the same value would simply be stored more than once.
+ *
+ * The restrictions for the algorithm to work properly are:
+ *
+ * 1) this code must be called at least once per each half period of the
+ *    32-bit counter;
+ *
+ * 2) this code must not be preempted for a duration longer than the
+ *    32-bit counter half period minus the longest period between two
+ *    calls to this code.
+ *
+ * Those requirements ensure proper update to the state bit in memory.
+ * This is usually not a problem in practice, but if it is then a kernel
+ * timer should be scheduled to manage for this code to be executed often
+ * enough.
+ *
+ * Note that the top bit (bit 63) in the returned value should be considered
+ * as garbage.  It is not cleared here because callers are likely to use a
+ * multiplier on the returned value which can get rid of the top bit
+ * implicitly by making the multiplier even, therefore saving on a runtime
+ * clear-bit instruction. Otherwise caller must remember to clear the top
+ * bit explicitly.

+ *     cpu_online_mask  - has bit 'cpu' set iff cpu available to scheduler
+ *     cpu_active_mask  - has bit 'cpu' set iff cpu available to migration
+ *
+ *  If !CONFIG_HOTPLUG_CPU, present == possible, and active == online.
+ *
+ *  The cpu_possible_mask is fixed at boot time, as the set of CPU id's
+ *  that it is possible might ever be plugged in at anytime during the
+ *  life of that system boot.  The cpu_present_mask is dynamic(*),
+ *  representing which CPUs are currently plugged in.  And
+ *  cpu_online_mask is the dynamic subset of cpu_present_mask,
+ *  indicating those CPUs available for scheduling.
+ *
+ *  If HOTPLUG is enabled, then cpu_possible_mask is forced to have
+ *  all NR_CPUS bits set, otherwise it is just the set of CPUs that
+ *  ACPI reports present at boot.
+ *
+ *  If HOTPLUG is enabled, then cpu_present_mask varies dynamically,
+ *  depending on what ACPI reports as currently plugged in, otherwise
+ *  cpu_present_mask is just a copy of cpu_possible_mask.
+ *
+ *  (*) Well, cpu_present_mask is dynamic in the hotplug case.  If not
+ *      hotplug, it's a copy of cpu_possible_mask, hence fixed at boot.
+ *
+ * Subtleties:
+ * 1) UP arch's (NR_CPUS == 1, CONFIG_SMP not defined) hardcode
+ *    assumption that their single CPU is online.  The UP
+ *    cpu_{online,possible,present}_masks are placebos.  Changing them
+ *    will have no useful affect on the following num_*_cpus()
+ *    and cpu_*() macros in the UP case.  This ugliness is a UP
+ *    optimization - don't waste any instructions or memory references
+ *    asking if you're online or how many CPUs there are if there is
+ *    only one CPU.

+ * [0x800000-0x1000000) are for additional space required by things
+ * like framebuffers. [0x400000-0x600000) is for miscellaneous internal I/O.
+ * On Linux, this is currently all mapped into the virtual address space
+ * at 0xf0000000 on bootup.
+ * DIO-II boards are at 0x1000000 + (sc - 132) * 0x400000
+ * which is address range [0x1000000-0x20000000) -- too big to map completely,
+ * so currently we just don't handle DIO-II boards.  It wouldn't be hard to

+ * Flags to dlm_lock

+ * DLM_LKF_NOQUEUE
+ *
+ * Do not queue the lock request on the wait queue if it cannot be granted
+ * immediately.  If the lock cannot be granted because of this flag, DLM will
+ * either return -EAGAIN from the dlm_lock call or will return 0 from
+ * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
+ *
+ * DLM_LKF_CANCEL
+ *
+ * Used to cancel a pending lock request or conversion.  A converting lock is
+ * returned to its previously granted mode.
+ *
+ * DLM_LKF_CONVERT
+ *
+ * Indicates a lock conversion request.  For conversions the name and namelen
+ * are ignored and the lock ID in the LKSB is used to identify the lock.
+ *
+ * DLM_LKF_VALBLK
+ *
+ * Requests DLM to return the current contents of the lock value block in the
+ * lock status block.  When this flag is set in a lock conversion from PW or EX
+ * modes, DLM assigns the value specified in the lock status block to the lock
+ * value block of the lock resource.  The LVB is a DLM_LVB_LEN size array
+ * containing application-specific information.
+ *
+ * DLM_LKF_QUECVT
+ *
+ * Force a conversion request to be queued, even if it is compatible with
+ * the granted modes of other locks on the same resource.
+ *
+ * DLM_LKF_IVVALBLK
+ *
+ * Invalidate the lock value block.
+ *
+ * DLM_LKF_CONVDEADLK
+ *
+ * Allows the dlm to resolve conversion deadlocks internally by demoting the
+ * granted mode of a converting lock to NL.  The DLM_SBF_DEMOTED flag is
+ * returned for a conversion that's been effected by this.
+ *
+ * DLM_LKF_PERSISTENT
+ *
+ * Only relevant to locks originating in userspace.  A persistent lock will not
+ * be removed if the process holding the lock exits.
+ *
+ * DLM_LKF_NODLCKWT
+ *
+ * Do not cancel the lock if it gets into conversion deadlock.
+ * Exclude this lock from being monitored due to DLM_LSFL_TIMEWARN.
+ *
+ * DLM_LKF_NODLCKBLK
+ *
+ * net yet implemented
+ *
+ * DLM_LKF_EXPEDITE
+ *
+ * Used only with new requests for NL mode locks.  Tells the lock manager
+ * to grant the lock, ignoring other locks in convert and wait queues.
+ *
+ * DLM_LKF_NOQUEUEBAST
+ *
+ * Send blocking AST's before returning -EAGAIN to the caller.  It is only
+ * used along with the NOQUEUE flag.  Blocking AST's are not sent for failed
+ * NOQUEUE requests otherwise.
+ *
+ * DLM_LKF_HEADQUE
+ *
+ * Add a lock to the head of the convert or wait queue rather than the tail.
+ *
+ * DLM_LKF_NOORDER
+ *
+ * Disregard the standard grant order rules and grant a lock as soon as it
+ * is compatible with other granted locks.
+ *
+ * DLM_LKF_ORPHAN
+ *
+ * not yet implemented
+ *
+ * DLM_LKF_ALTPR
+ *
+ * If the requested mode cannot be granted immediately, try to grant the lock
+ * in PR mode instead.  If this alternate mode is granted instead of the
+ * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
+ *
+ * DLM_LKF_ALTCW
+ *
+ * The same as ALTPR, but the alternate mode is CW.
+ *
+ * DLM_LKF_FORCEUNLOCK
+ *
+ * Unlock the lock even if it is converting or waiting or has sublocks.
+ * Only really for use by the userland device.c code.

+ * slots will be filled.  The device will be in suspended state
+ * after creation, however any io to the device will get errored
+ * since it will be out-of-bounds.
+ *
+ * DM_DEV_REMOVE:
+ * Remove a device, destroy any tables.
+ *
+ * DM_DEV_RENAME:
+ * Rename a device.
+ *
+ * DM_SUSPEND:
+ * This performs both suspend and resume, depending which flag is
+ * passed in.
+ * Suspend: This command will not return until all pending io to
+ * the device has completed.  Further io will be deferred until
+ * the device is resumed.
+ * Resume: It is no longer an error to issue this command on an
+ * unsuspended device.  If a table is present in the 'inactive'
+ * slot, it will be moved to the active slot, then the old table
+ * from the active slot will be _destroyed_.  Finally the device
+ * is resumed.
+ *
+ * DM_DEV_STATUS:
+ * Retrieves the status for the table in the 'active' slot.
+ *
+ * DM_DEV_WAIT:
+ * Wait for a significant event to occur to the device.  This
+ * could either be caused by an event triggered by one of the
+ * targets of the table in the 'active' slot, or a table change.
+ *
+ * DM_TABLE_LOAD:
+ * Load a table into the 'inactive' slot for the device.  The
+ * device does _not_ need to be suspended prior to this command.
+ *
+ * DM_TABLE_CLEAR:
+ * Destroy any table in the 'inactive' slot (ie. abort).
+ *
+ * DM_TABLE_DEPS:
+ * Return a set of device dependencies for the 'active' table.
+ *
+ * DM_TABLE_STATUS:
+ * Return the targets status for the 'active' table.
+ *
+ * DM_TARGET_MSG:
+ * Pass a message string to the target at a specific offset of a device.
+ *
+ * DM_DEV_SET_GEOMETRY:
+ * Set the geometry of a device by passing in a string in this format:
+ *
+ * "cylinders heads sectors_per_track start_sector"
+ *
+ * Beware that CHS geometry is nearly obsolete and only provided
+ * for compatibility with dm devices that can be booted by a PC

+ * The device-mapper userspace log module consists of a kernel component and
+ * a user-space component.  The kernel component implements the API defined
+ * in dm-dirty-log.h.  Its purpose is simply to pass the parameters and
+ * return values of those API functions between kernel and user-space.
+ *
+ * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
+ * These request types represent the different functions in the device-mapper
+ * dirty log API.  Each of these is described in more detail below.
+ *
+ * The user-space program must listen for requests from the kernel (representing
+ * the various API functions) and process them.
+ *
+ * User-space begins by setting up the communication link (error checking
+ * removed for clarity):
+ *	fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+ *	addr.nl_family = AF_NETLINK;
+ *	addr.nl_groups = CN_IDX_DM;
+ *	addr.nl_pid = 0;
+ *	r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
+ *	opt = addr.nl_groups;
+ *	setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
+ *
+ * User-space will then wait to receive requests form the kernel, which it
+ * will process as described below.  The requests are received in the form,
+ * ((struct dm_ulog_request) + (additional data)).  Depending on the request
+ * type, there may or may not be 'additional data'.  In the descriptions below,
+ * you will see 'Payload-to-userspace' and 'Payload-to-kernel'.  The
+ * 'Payload-to-userspace' is what the kernel sends in 'additional data' as
+ * necessary parameters to complete the request.  The 'Payload-to-kernel' is
+ * the 'additional data' returned to the kernel that contains the necessary
+ * results of the request.  The 'data_size' field in the dm_ulog_request

+ * "desc" field is the actual data.  There are no constraints on the
+ * desc field's contents, though typically they're fairly small.
+ *
+ * All notes from a given NAME are put into a section named
+ * .note.NAME.  When the kernel image is finally linked, all the notes

+ * @fh_to_parent:   find the implied object's parent and get a dentry for it
+ * @get_name:       find the name for a given inode in a given directory
+ * @get_parent:     find the parent of a given directory
+ *
+ * See Documentation/filesystems/nfs/Exporting for details on how to use
+ * this interface correctly.
+ *
+ * encode_fh:
+ *    @encode_fh should store in the file handle fragment @fh (using at most
+ *    @max_len bytes) information that can be used by @decode_fh to recover the
+ *    file refered to by the &struct dentry @de.  If the @connectable flag is
+ *    set, the encode_fh() should store sufficient information so that a good
+ *    attempt can be made to find not only the file but also it's place in the
+ *    filesystem.   This typically means storing a reference to de->d_parent in
+ *    the filehandle fragment.  encode_fh() should return the number of bytes
+ *    stored or a negative error code such as %-ENOSPC
+ *
+ * fh_to_dentry:
+ *    @fh_to_dentry is given a &struct super_block (@sb) and a file handle
+ *    fragment (@fh, @fh_len). It should return a &struct dentry which refers
+ *    to the same file that the file handle fragment refers to.  If it cannot,
+ *    it should return a %NULL pointer if the file was found but no acceptable
+ *    &dentries were available, or an %ERR_PTR error code indicating why it
+ *    couldn't be found (e.g. %ENOENT or %ENOMEM).  Any suitable dentry can be
+ *    returned including, if necessary, a new dentry created with d_alloc_root.
+ *    The caller can then find any other extant dentries by following the
+ *    d_alias links.
+ *
+ * fh_to_parent:
+ *    Same as @fh_to_dentry, except that it returns a pointer to the parent
+ *    dentry if it was encoded into the filehandle fragment by @encode_fh.
+ *
+ * get_name:
+ *    @get_name should find a name for the given @child in the given @parent
+ *    directory.  The name should be stored in the @name (with the
+ *    understanding that it is already pointing to a a %NAME_MAX+1 sized
+ *    buffer.   get_name() should return %0 on success, a negative error code
+ *    or error.  @get_name will be called without @parent->i_mutex held.
+ *
+ * get_parent:
+ *    @get_parent should find the parent directory for the given @child which
+ *    is also a directory.  In the event that it cannot be found, or storage
+ *    space cannot be allocated, a %ERR_PTR should be returned.
+ *
+ * Locking rules:
+ *    get_parent is called with child->d_inode->i_mutex down
+ *    get_name is not (which is possibly inconsistent)

+ * The below are the various read and write types that we support. Some of
+ * them include behavioral modifiers that send information down to the
+ * block layer and IO scheduler. Terminology:
+ *
+ *	The block layer uses device plugging to defer IO a little bit, in
+ *	the hope that we will see more IO very shortly. This increases
+ *	coalescing of adjacent IO and thus reduces the number of IOs we
+ *	have to send to the device. It also allows for better queuing,
+ *	if the IO isn't mergeable. If the caller is going to be waiting
+ *	for the IO, then he must ensure that the device is unplugged so
+ *	that the IO is dispatched to the driver.
+ *
+ *	All IO is handled async in Linux. This is fine for background
+ *	writes, but for reads or writes that someone waits for completion
+ *	on, we want to notify the block layer and IO scheduler so that they
+ *	know about it. That allows them to make better scheduling
+ *	decisions. So when the below references 'sync' and 'async', it
+ *	is referencing this priority hint.
+ *
+ * With that in mind, the available types are:
+ *
+ * READ			A normal read operation. Device will be plugged.
+ * READ_SYNC		A synchronous read. Device is not plugged, caller can
+ *			immediately wait on this read without caring about
+ *			unplugging.
+ * READA		Used for read-ahead operations. Lower priority, and the
+ *			 block layer could (in theory) choose to ignore this
+ *			request if it runs into resource problems.
+ * WRITE		A normal async write. Device will be plugged.
+ * SWRITE		Like WRITE, but a special case for ll_rw_block() that
+ *			tells it to lock the buffer first. Normally a buffer
+ *			must be locked before doing IO.
+ * WRITE_SYNC_PLUG	Synchronous write. Identical to WRITE, but passes down
+ *			the hint that someone will be waiting on this IO
+ *			shortly. The device must still be unplugged explicitly,
+ *			WRITE_SYNC_PLUG does not do this as we could be
+ *			submitting more writes before we actually wait on any
+ *			of them.
+ * WRITE_SYNC		Like WRITE_SYNC_PLUG, but also unplugs the device
+ *			immediately after submission. The write equivalent
+ *			of READ_SYNC.
+ * WRITE_ODIRECT_PLUG	Special case write for O_DIRECT only.
+ * SWRITE_SYNC
+ * SWRITE_SYNC_PLUG	Like WRITE_SYNC/WRITE_SYNC_PLUG, but locks the buffer.
+ *			See SWRITE.
+ * WRITE_BARRIER	Like WRITE, but tells the block layer that all
+ *			previously submitted writes must be safely on storage
+ *			before this one is started. Also guarantees that when
+ *			this write is complete, it itself is also safely on
+ *			storage. Prevents reordering of writes on both sides
+ *			of this IO.

+ * Inode state bits.  Protected by inode_lock.
+ *
+ * Three bits determine the dirty state of the inode, I_DIRTY_SYNC,
+ * I_DIRTY_DATASYNC and I_DIRTY_PAGES.
+ *
+ * Four bits define the lifetime of an inode.  Initially, inodes are I_NEW,
+ * until that flag is cleared.  I_WILL_FREE, I_FREEING and I_CLEAR are set at
+ * various stages of removing an inode.
+ *
+ * Two bits are used for locking and completion notification, I_NEW and I_SYNC.
+ *
+ * I_DIRTY_SYNC		Inode is dirty, but doesn't have to be written on
+ *			fdatasync().  i_atime is the usual cause.
+ * I_DIRTY_DATASYNC	Data-related inode changes pending. We keep track of
+ *			these changes separately from I_DIRTY_SYNC so that we
+ *			don't have to write inode on fdatasync() when only
+ *			mtime has changed in it.
+ * I_DIRTY_PAGES	Inode has dirty pages.  Inode itself may be clean.
+ * I_NEW		Serves as both a mutex and completion notification.
+ *			New inodes set I_NEW.  If two processes both create
+ *			the same inode, one of them will release its inode and
+ *			wait for I_NEW to be released before returning.
+ *			Inodes in I_WILL_FREE, I_FREEING or I_CLEAR state can
+ *			also cause waiting on I_NEW, without I_NEW actually
+ *			being set.  find_inode() uses this to prevent returning
+ *			nearly-dead inodes.
+ * I_WILL_FREE		Must be set when calling write_inode_now() if i_count
+ *			is zero.  I_FREEING must be set when I_WILL_FREE is
+ *			cleared.
+ * I_FREEING		Set when inode is about to be freed but still has dirty
+ *			pages or buffers attached or the inode itself is still
+ *			dirty.
+ * I_CLEAR		Set by clear_inode().  In this state the inode is clean
+ *			and can be destroyed.
+ *
+ *			Inodes that are I_WILL_FREE, I_FREEING or I_CLEAR are
+ *			prohibited for many purposes.  iget() must wait for
+ *			the inode to be completely released, then create it
+ *			anew.  Other functions will just ignore such inodes,
+ *			if appropriate.  I_NEW is used for waiting.
+ *
+ * I_SYNC		Synchonized write of dirty inode data.  The bits is
+ *			set during data writeback, and cleared with a wakeup
+ *			on the bit address once it is done.
+ *
+ * Q: What is the difference between I_WILL_FREE and I_FREEING?

+ * Except when I2C "protocol mangling" is used, all I2C adapters implement
+ * the standard rules for I2C transactions.  Each transaction begins with a
+ * START.  That is followed by the slave address, and a bit encoding read
+ * versus write.  Then follow all the data bytes, possibly including a byte
+ * with SMBus PEC.  The transfer terminates with a NAK, or when all those
+ * bytes have been transferred and ACKed.  If this is the last message in a
+ * group, it is followed by a STOP.  Otherwise it is followed by the next
+ * @i2c_msg transaction segment, beginning with a (repeated) START.
+ *
+ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then
+ * passing certain @flags may have changed those standard protocol behaviors.
+ * Those flags are only for use with broken/nonconforming slaves, and with
+ * adapters which are known to support the specific mangling options they
+ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR).

+ * struct input_dev - represents an input device
+ * @name: name of the device
+ * @phys: physical path to the device in the system hierarchy
+ * @uniq: unique identification code for the device (if device has it)
+ * @id: id of the device (struct input_id)
+ * @evbit: bitmap of types of events supported by the device (EV_KEY,
+ *	EV_REL, etc.)
+ * @keybit: bitmap of keys/buttons this device has
+ * @relbit: bitmap of relative axes for the device
+ * @absbit: bitmap of absolute axes for the device
+ * @mscbit: bitmap of miscellaneous events supported by the device
+ * @ledbit: bitmap of leds present on the device
+ * @sndbit: bitmap of sound effects supported by the device
+ * @ffbit: bitmap of force feedback effects supported by the device
+ * @swbit: bitmap of switches present on the device
+ * @keycodemax: size of keycode table
+ * @keycodesize: size of elements in keycode table
+ * @keycode: map of scancodes to keycodes for this device
+ * @setkeycode: optional method to alter current keymap, used to implement
+ *	sparse keymaps. If not supplied default mechanism will be used.
+ *	The method is being called while holding event_lock and thus must
+ *	not sleep
+ * @getkeycode: optional method to retrieve current keymap. If not supplied
+ *	default mechanism will be used. The method is being called while
+ *	holding event_lock and thus must not sleep
+ * @ff: force feedback structure associated with the device if device
+ *	supports force feedback effects
+ * @repeat_key: stores key code of the last key pressed; used to implement
+ *	software autorepeat
+ * @timer: timer for software autorepeat
+ * @sync: set to 1 when there were no new events since last EV_SYNC
+ * @abs: current values for reports from absolute axes
+ * @rep: current values for autorepeat parameters (delay, rate)
+ * @key: reflects current state of device's keys/buttons
+ * @led: reflects current state of device's LEDs
+ * @snd: reflects current state of sound effects
+ * @sw: reflects current state of device's switches
+ * @absmax: maximum values for events coming from absolute axes
+ * @absmin: minimum values for events coming from absolute axes
+ * @absfuzz: describes noisiness for axes
+ * @absflat: size of the center flat position (used by joydev)
+ * @absres: resolution used for events coming form absolute axes
+ * @open: this method is called when the very first user calls
+ *	input_open_device(). The driver must prepare the device
+ *	to start generating events (start polling thread,
+ *	request an IRQ, submit URB, etc.)
+ * @close: this method is called when the very last user calls
+ *	input_close_device().
+ * @flush: purges the device. Most commonly used to get rid of force
+ *	feedback effects loaded into the device when disconnecting
+ *	from it
+ * @event: event handler for events sent _to_ the device, like EV_LED
+ *	or EV_SND. The device is expected to carry out the requested
+ *	action (turn on a LED, play sound, etc.) The call is protected
+ *	by @event_lock and must not sleep
+ * @grab: input handle that currently has the device grabbed (via
+ *	EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
+ *	recipient for all input events coming from the device
+ * @event_lock: this spinlock is is taken when input core receives
+ *	and processes a new event for the device (in input_event()).
+ *	Code that accesses and/or modifies parameters of a device
+ *	(such as keymap or absmin, absmax, absfuzz, etc.) after device
+ *	has been registered with input core must take this lock.
+ * @mutex: serializes calls to open(), close() and flush() methods
+ * @users: stores number of users (input handlers) that opened this
+ *	device. It is used by input_open_device() and input_close_device()
+ *	to make sure that dev->open() is only called when the first
+ *	user opens device and dev->close() is called when the very
+ *	last user closes the device
+ * @going_away: marks devices that are in a middle of unregistering and
+ *	causes input_open_device*() fail with -ENODEV.
+ * @dev: driver model's view of this device
+ * @h_list: list of input handles associated with the device. When
+ *	accessing the list dev->mutex must be held
+ * @node: used to place the device onto input_dev_list

+ * This file describes an interface to an IPMI driver.  You have to
+ * have a fairly good understanding of IPMI to use this, so go read
+ * the specs first before actually trying to do anything.
+ *
+ * With that said, this driver provides a multi-user interface to the
+ * IPMI driver, and it allows multiple IPMI physical interfaces below
+ * the driver.  The physical interfaces bind as a lower layer on the
+ * driver.  They appear as interfaces to the application using this
+ * interface.
+ *
+ * Multi-user means that multiple applications may use the driver,
+ * send commands, receive responses, etc.  The driver keeps track of
+ * commands the user sends and tracks the responses.  The responses
+ * will go back to the application that send the command.  If the
+ * response doesn't come back in time, the driver will return a
+ * timeout error response to the application.  Asynchronous events
+ * from the BMC event queue will go to all users bound to the driver.
+ * The incoming event queue in the BMC will automatically be flushed
+ * if it becomes full and it is queried once a second to see if
+ * anything is in it.  Incoming commands to the driver will get
+ * delivered as commands.
+ *
+ * This driver provides two main interfaces: one for in-kernel
+ * applications and another for userland applications.  The
+ * capabilities are basically the same for both interface, although
+ * the interfaces are somewhat different.  The stuff in the
+ * #ifdef __KERNEL__ below is the in-kernel interface.  The userland
+ * interface is defined later in the file.  */

+*
+* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
+* Call Progress Tones (CPT).  This is accomplished by setting up an array of
+* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
+* the tone sequence.  The tone_on_time and tone_off time are in
+* 250 microsecond intervals.  A pointer to this array is passed to the
+* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
+* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
+* termination variable defines what to do at the end of a cadence, the
+* options are to play the cadence once and stop, to repeat the last
+* element of the cadence indefinitely, or to repeat the entire cadence
+* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
+* structures.  If the freq0 variable is non-zero, the tone table contents
+* for the tone_index are updated to the frequencies and gains defined.  It
+* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
+* table indexes are used in a cadence the frequency and gain variables will
+* be ignored.
+*
+* If the array elements contain frequency parameters the driver will
+* initialize the needed tone table elements and begin playing the tone,
+* there is no preset limit on the number of elements in the cadence.  If
+* there is more than one frequency used in the cadence, sequential elements
+* of different frequencies MUST use different tone table indexes.  Only one
+* cadence can be played at a time.  It is possible to build complex
+* cadences with multiple frequencies using 2 tone table indexes by

+ * We want to do realistic conversions of time so we need to use the same

+ * is: TICK_NSEC (which is defined in timex.h).  This
+ * is a constant and is in nanoseconds.  We will use scaled math
+ * with a set of scales defined here as SEC_JIFFIE_SC,  USEC_JIFFIE_SC and
+ * NSEC_JIFFIE_SC.  Note that these defines contain nothing but
+ * constants and so are computed at compile time.  SHIFT_HZ (computed in
+ * timex.h) adjusts the scaling for different HZ values.
+
+ * Scaled math???  What is that?
+ *
+ * Scaled math is a way to do integer math on values that would,
+ * otherwise, either overflow, underflow, or cause undesired div
+ * instructions to appear in the execution path.  In short, we "scale"
+ * up the operands so they take more bits (more precision, less
+ * underflow), do the desired operation and then "scale" the result back
+ * by the same amount.  If we do the scaling by shifting we avoid the
+ * costly mpy and the dastardly div instructions.
+
+ * Suppose, for example, we want to convert from seconds to jiffies
+ * where jiffies is defined in nanoseconds as NSEC_PER_JIFFIE.  The
+ * simple math is: jiff = (sec * NSEC_PER_SEC) / NSEC_PER_JIFFIE; We
+ * observe that (NSEC_PER_SEC / NSEC_PER_JIFFIE) is a constant which we
+ * might calculate at compile time, however, the result will only have
+ * about 3-4 bits of precision (less for smaller values of HZ).
+ *
+ * So, we scale as follows:
+ * jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE);
+ * jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE;
+ * Then we make SCALE a power of two so:
+ * jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE;
+ * Now we define:
+ * #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE))
+ * jiff = (sec * SEC_CONV) >> SCALE;
+ *
+ * Often the math we use will expand beyond 32-bits so we tell C how to
+ * do this and pass the 64-bit result of the mpy through the ">> SCALE"
+ * which should take the result back to 32-bits.  We want this expansion
+ * to capture as much precision as possible.  At the same time we don't
+ * want to overflow so we pick the SCALE to avoid this.  In this file,
+ * that means using a different scale for each range of HZ values (as
+ * defined in timex.h).
+ *
+ * For those who want to know, gcc will give a 64-bit result from a "*"
+ * operator if the result is a long long AND at least one of the
+ * operands is cast to long long (usually just prior to the "*" so as
+ * not to confuse it into thinking it really has a 64-bit operand,
+ * which, buy the way, it can do, but it takes more code and at least 2
+ * mpys).
+
+ * We also need to be aware that one second in nanoseconds is only a
+ * couple of bits away from overflowing a 32-bit word, so we MUST use
+ * 64-bits to get the full range time in nanoseconds.
+
+ */
+
+/*
+ * Here are the scales we will use.  One for seconds, nanoseconds and
+ * microseconds.
+ *
+ * Within the limits of cpp we do a rough cut at the SEC_JIFFIE_SC and
+ * check if the sign bit is set.  If not, we bump the shift count by 1.
+ * (Gets an extra bit of precision where we can use it.)
+ * We know it is set for HZ = 1024 and HZ = 100 not for 1000.

+This header file (and its .c file; kernel-doc of functions see there)
+  define a helper framework to easily keep track of index:label associations,
+  and changes to an "active set" of objects, as well as pending transactions,
+  to persistently record those changes.
+
+  We use an LRU policy if it is necessary to "cool down" a region currently in
+  the active set before we can "heat" a previously unused region.
+
+  Because of this later property, it is called "lru_cache".
+  As it actually Tracks Objects in an Active SeT, we could also call it
+  toast (incidentally that is what may happen to the data on the
+  backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+  we need to resync all regions that have been target of in-flight WRITE IO
+  (in use, or "hot", regions), as we don't know wether or not those WRITEs have
+  made it to stable storage.
+
+  To avoid a "full resync", we need to persistently track these regions.
+
+  This is known as "write intent log", and can be implemented as on-disk
+  (coarse or fine grained) bitmap, or other meta data.
+
+  To avoid the overhead of frequent extra writes to this meta data area,
+  usually the condition is softened to regions that _may_ have been target of
+  in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+  bitmap, trading frequency of meta data transactions against amount of
+  (possibly unneccessary) resync traffic.
+
+  If we set a hard limit on the area that may be "hot" at any given time, we
+  limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+  we need to resync all blocks that have been changed on the other replica
+  in the mean time, or, if both replica have been changed independently [*],
+  all blocks that have been changed on either replica in the mean time.
+  [*] usually as a result of a cluster split-brain and insufficient protection.
+      but there are valid use cases to do this on purpose.
+
+  Tracking those blocks can be implemented as "dirty bitmap".
+  Having it fine-grained reduces the amount of resync traffic.
+  It should also be persistent, to allow for reboots (or crashes)
+  while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+  The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+  To reduce the frequency of bitmap updates for write-intent log purposes,
+  one could dirty "chunks" (of some size) at a time of the (fine grained)
+  on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+  possible, flushing it to disk again when a previously "hot" (and on-disk
+  dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+  and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+  An other implementation could chose a (probably coarse) explicit bitmap,
+  for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+  Yet an other implementation may keep track of the hot regions, by starting
+  with an empty set, and writing down a journal of region numbers that have
+  become "hot", or have "cooled down" again.
+
+  To be able to use a ring buffer for this journal of changes to the active
+  set, we not only record the actual changes to that set, but also record the
+  not changing members of the set in a round robin fashion. To do so, we use a
+  fixed (but configurable) number of slots which we can identify by index, and
+  associate region numbers (labels) with these indices.
+  For each transaction recording a change to the active set, we record the
+  change itself (index: -old_label, +new_label), and which index is associated
+  with which label (index: current_label) within a certain sliding window that
+  is moved further over the available indices with each such transaction.
+
+  Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+  accurately reconstruct the active set.
+
+  Sufficiently large depends only on maximum number of active objects, and the
+  size of the sliding window recording "index: current_label" associations within
+  each transaction.
+
+  This is what we call the "activity log".
+
+  Currently we need one activity log transaction per single label change, which
+  does not give much benefit over the "dirty chunks of bitmap" approach, other
+  than potentially less seeks.
+
+  We plan to change the transaction format to support multiple changes per
+  transaction, which then would reduce several (disjoint, "random") updates to
+  the bitmap into one transaction to the activity log ring buffer.
+*/
+
+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily.  To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ *  in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ *     lru: unused but ready to be reused or recycled
+ *          (ts_refcnt == 0, lc_number != LC_FREE),
+ *    free: unused but ready to be recycled
+ *          (ts_refcnt == 0, lc_number == LC_FREE),
+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architechture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well.  Which also means that using a kmem_cache to allocate the objects
+ * from wastes some resources.
+ * But it avoids high order page allocations in kmalloc.

+ *   page_count() == 0 means the page is free. page->lru is then used for
+ *   freelist management in the buddy allocator.
+ *   page_count() > 0  means the page has been allocated.
+ *
+ * Pages are allocated by the slab allocator in order to provide memory
+ * to kmalloc and kmem_cache_alloc. In this case, the management of the
+ * page, and the fields in 'struct page' are the responsibility of mm/slab.c
+ * unless a particular usage is carefully commented. (the responsibility of
+ * freeing the kmalloc memory is the caller's, of course).
+ *
+ * A page may be used by anyone else who does a __get_free_page().
+ * In this case, page_count still tracks the references, and should only
+ * be used through the normal accessor functions. The top bits of page->flags
+ * and page->virtual store page management information, but all other fields
+ * are unused and could be used privately, carefully. The management of this
+ * page is the responsibility of the one who allocated it, and those who have
+ * subsequently been given references to it.
+ *
+ * The other pages (we may call them "pagecache pages") are completely
+ * managed by the Linux memory manager: I/O, buffers, swapping etc.
+ * The following discussion applies only to them.
+ *
+ * A pagecache page contains an opaque `private' member, which belongs to the
+ * page's address_space. Usually, this is the address of a circular list of
+ * the page's disk buffers. PG_private must be set to tell the VM to call
+ * into the filesystem to release these pages.
+ *
+ * A page may belong to an inode's memory mapping. In this case, page->mapping
+ * is the pointer to the inode, and page->index is the file offset of the page,
+ * in units of PAGE_CACHE_SIZE.
+ *
+ * If pagecache pages are not associated with an inode, they are said to be
+ * anonymous pages. These may become associated with the swapcache, and in that
+ * case PG_swapcache is set, and page->private is an offset into the swapcache.
+ *
+ * In either case (swapcache or inode backed), the pagecache itself holds one
+ * reference to the page. Setting PG_private should also increment the
+ * refcount. The each user mapping also has a reference to the page.
+ *
+ * The pagecache pages are stored in a per-mapping radix tree, which is
+ * rooted at mapping->page_tree, and indexed by offset.
+ * Where 2.4 and early 2.6 kernels kept dirty/clean pages in per-address_space
+ * lists, we instead now tag pages as dirty/writeback in the radix tree.
+ *
+ * All pagecache pages may be subject to I/O:
+ * - inode pages may need to be read from disk,
+ * - inode pages which have been modified and are MAP_SHARED may need
+ *   to be written back to the inode on disk,
+ * - anonymous pages (including MAP_PRIVATE file mappings) which have been
+ *   modified may need to be swapped out to swap space and (later) to be read
+ *   back into memory.

+ *
+ * 1) The BITMAP fullzones tracks which zones in a zonelist have come
+ *    up short of free memory since the last time (last_fullzone_zap)
+ *    we zero'd fullzones.
+ * 2) The array z_to_n[] maps each zone in the zonelist to its node
+ *    id, so that we can efficiently evaluate whether that node is
+ *    set in the current tasks mems_allowed.
+ *
+ * Both fullzones and z_to_n[] are one-to-one with the zonelist,
+ * indexed by a zones offset in the zonelist zones[] array.
+ *
+ * The get_page_from_freelist() routine does two scans.  During the
+ * first scan, we skip zones whose corresponding bit in 'fullzones'
+ * is set or whose corresponding node in current->mems_allowed (which
+ * comes from cpusets) is not set.  During the second scan, we bypass
+ * this zonelist_cache, to ensure we look methodically at each zone.
+ *
+ * Once per second, we zero out (zap) fullzones, forcing us to
+ * reconsider nodes that might have regained more free memory.
+ * The field last_full_zap is the time we last zapped fullzones.
+ *
+ * This mechanism reduces the amount of time we waste repeatedly
+ * reexaming zones for free memory when they just came up low on
+ * memory momentarilly ago.
+ *
+ * The zonelist_cache struct members logically belong in struct
+ * zonelist.  However, the mempolicy zonelists constructed for
+ * MPOL_BIND are intentionally variable length (and usually much
+ * shorter).  A general purpose mechanism for handling structs with
+ * multiple variable length members is more mechanism than we want
+ * here.  We resort to some special case hackery instead.
+ *
+ * The MPOL_BIND zonelists don't need this zonelist_cache (in good
+ * part because they are shorter), so we put the fixed length stuff
+ * at the front of the zonelist struct, ending in a variable length
+ * zones[], as is needed by MPOL_BIND.
+ *
+ * Then we put the optional zonelist cache on the end of the zonelist
+ * struct.  This optional stuff is found by a 'zlcache_ptr' pointer in
+ * the fixed length portion at the front of the struct.  This pointer
+ * both enables us to find the zonelist cache, and in the case of
+ * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
+ * to know that the zonelist cache is not there.
+ *
+ * The end result is that struct zonelists come in two flavors:
+ *  1) The full, fixed length version, shown below, and
+ *  2) The custom zonelists for MPOL_BIND.
+ * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
+ *
+ * Even though there may be multiple CPU cores on a node modifying
+ * fullzones or last_full_zap in the same zonelist_cache at the same
+ * time, we don't lock it.  This is just hint data - if it is wrong now
+ * and then, the allocator will still function, perhaps a bit slower.

+ *	although some only make sense in conjunction with other fields.
+ *	This is usually set by a USB_DEVICE_*() macro, which sets all
+ *	other fields in this structure except for driver_info.
+ * @idVendor: USB vendor ID for a device; numbers are assigned
+ *	by the USB forum to its members.
+ * @idProduct: Vendor-assigned product ID.
+ * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
+ *	This is also used to identify individual product versions, for
+ *	a range consisting of a single device.
+ * @bcdDevice_hi: High end of version number range.  The range of product
+ *	versions is inclusive.
+ * @bDeviceClass: Class of device; numbers are assigned
+ *	by the USB forum.  Products may choose to implement classes,
+ *	or be vendor-specific.  Device classes specify behavior of all
+ *	the interfaces on a devices.
+ * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
+ * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
+ * @bInterfaceClass: Class of interface; numbers are assigned
+ *	by the USB forum.  Products may choose to implement classes,
+ *	or be vendor-specific.  Interface classes specify behavior only
+ *	of a given interface; other interfaces may support other classes.
+ * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
+ * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
+ * @driver_info: Holds information used by the driver.  Usually it holds
+ *	a pointer to a descriptor understood by the driver, or perhaps
+ *	device flags.
+ *
+ * In most cases, drivers will create a table of device IDs by using
+ * USB_DEVICE(), or similar macros designed for that purpose.
+ * They will then export it to userspace using MODULE_DEVICE_TABLE(),
+ * and provide it to the USB core through their usb_driver structure.
+ *
+ * See the usb_match_id() function for information about how matches are
+ * performed.  Briefly, you will normally use one of several macros to help
+ * construct these entries.  Each entry you provide will either identify
+ * one or more specific products, or will identify a class of products
+ * which have agreed to behave the same.  You should put the more specific
+ * matches towards the beginning of your table, so that driver_info can
+ * record quirks of specific products.

+ * @ubi_num: UBI device number this volume belongs to
+ * @size: how many physical eraseblocks are reserved for this volume
+ * @used_bytes: how many bytes of data this volume contains
+ * @used_ebs: how many physical eraseblocks of this volume actually contain any
+ *            data
+ * @vol_type: volume type (%UBI_DYNAMIC_VOLUME or %UBI_STATIC_VOLUME)
+ * @corrupted: non-zero if the volume is corrupted (static volumes only)
+ * @upd_marker: non-zero if the volume has update marker set
+ * @alignment: volume alignment
+ * @usable_leb_size: how many bytes are available in logical eraseblocks of
+ *                   this volume
+ * @name_len: volume name length
+ * @name: volume name
+ * @cdev: UBI volume character device major and minor numbers
+ *
+ * The @corrupted flag is only relevant to static volumes and is always zero
+ * for dynamic ones. This is because UBI does not care about dynamic volume
+ * data protection and only cares about protecting static volume data.
+ *
+ * The @upd_marker flag is set if the volume update operation was interrupted.
+ * Before touching the volume data during the update operation, UBI first sets
+ * the update marker flag for this volume. If the volume update operation was
+ * further interrupted, the update marker indicates this. If the update marker
+ * is set, the contents of the volume is certainly damaged and a new volume
+ * update operation has to be started.
+ *
+ * To put it differently, @corrupted and @upd_marker fields have different
+ * semantics:
+ *     o the @corrupted flag means that this static volume is corrupted for some
+ *       reasons, but not because an interrupted volume update
+ *     o the @upd_marker field means that the volume is damaged because of an
+ *       interrupted update operation.
+ *
+ * I.e., the @corrupted flag is never set if the @upd_marker flag is set.
+ *
+ * The @used_bytes and @used_ebs fields are only really needed for static
+ * volumes and contain the number of bytes stored in this static volume and how
+ * many eraseblock this data occupies. In case of dynamic volumes, the
+ * @used_bytes field is equivalent to @size*@usable_leb_size, and the @used_ebs
+ * field is equivalent to @size.
+ *
+ * In general, logical eraseblock size is a property of the UBI device, not
+ * of the UBI volume. Indeed, the logical eraseblock size depends on the
+ * physical eraseblock size and on how much bytes UBI headers consume. But
+ * because of the volume alignment (@alignment), the usable size of logical
+ * eraseblocks if a volume may be less. The following equation is true:
+ * 	@usable_leb_size = LEB size - (LEB size mod @alignment),
+ * where LEB size is the logical eraseblock size defined by the UBI device.
+ *
+ * The alignment is multiple to the minimal flash input/output unit size or %1
+ * if all the available space is used.
+ *
+ * To put this differently, alignment may be considered is a way to change
+ * volume logical eraseblock sizes.

+ * ip_conntrack_h323_asn1.h - BER and PER decoding library for H.323
+ * 			      conntrack/NAT module.
+ *
+ * Copyright (c) 2006 by Jing Min Zhao <zhaojingmin@users.sourceforge.net>
+ *
+ * This source code is licensed under General Public License version 2.
+ *
+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245
+ * version 7. It is extremely optimized to decode only the absolutely
+ * necessary objects in a signal for Linux kernel NAT module use, so don't
+ * expect it to be a full ASN.1 library.
+ *
+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ *    takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ *    cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ *    support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ *    If a Setup signal contains more than 30 faststart, the packet size will
+ *    very likely exceed the MTU size, then the TPKT will be fragmented. I
+ *    don't know how to handle this in a Netfilter module. Anybody can help?
+ *    Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.

+ * (in `cmp' array). This is quick as it requires only two elementary
+ * number comparisons in worst case. Further, we take advantage of
+ * fact that entropy of 3 last bytes of address is larger than entropy
+ * of 3 first bytes. So first we compare 4 last bytes of addresses and

+ * This is the new flexible, extensible style NFSv2/v3 file handle.
+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
+ *
+ * The file handle is seens as a list of 4byte words.
+ * The first word contains a version number (1) and four descriptor bytes
+ * that tell how the remaining 3 variable length fields should be handled.
+ * These three bytes are auth_type, fsid_type and fileid_type.
+ *
+ * All 4byte values are in host-byte-order.
+ *
+ * The auth_type field specifies how the filehandle can be authenticated
+ * This might allow a file to be confirmed to be in a writable part of a
+ * filetree without checking the path from it upto the root.
+ * Current values:
+ *     0  - No authentication.  fb_auth is 0 bytes long
+ * Possible future values:
+ *     1  - 4 bytes taken from MD5 hash of the remainer of the file handle
+ *          prefixed by a secret and with the important export flags.
+ *
+ * The fsid_type identifies how the filesystem (or export point) is
+ *    encoded.
+ *  Current values:
+ *     0  - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
+ *        NOTE: we cannot use the kdev_t device id value, because kdev_t.h
+ *              says we mustn't.  We must break it up and reassemble.
+ *     1  - 4 byte user specified identifier
+ *     2  - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
+ *     3  - 4 byte device id, encoded for user-space, 4 byte inode number
+ *     4  - 4 byte inode number and 4 byte uuid
+ *     5  - 8 byte uuid
+ *     6  - 16 byte uuid
+ *     7  - 8 byte inode number and 16 byte uuid
+ *
+ * The fileid_type identified how the file within the filesystem is encoded.
+ * This is (will be) passed to, and set by, the underlying filesystem if it supports
+ * filehandle operations.  The filesystem must not use the value '0' or '0xff' and may
+ * only use the values 1 and 2 as defined below:
+ *  Current values:
+ *    0   - The root, or export point, of the filesystem.  fb_fileid is 0 bytes.
+ *    1   - 32bit inode number, 32 bit generation number.
+ *    2   - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.

+ *
+ * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
+ *	interface is identified with %NL80211_ATTR_IFINDEX and the management
+ *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
+ *	added to the end of the specified management frame is specified with
+ *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
+ *	added to all specified management frames generated by
+ *	kernel/firmware/driver.
+ *	Note: This command has been removed and it is only reserved at this
+ *	point to avoid re-using existing command number. The functionality this
+ *	command was planned for has been provided with cleaner design with the
+ *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
+ *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
+ *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
+ *
+ * @NL80211_CMD_GET_SCAN: get scan results
+ * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
+ * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
+ *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
+ * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
+ *	partial scan results may be available
+ *
+ * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
+ *      or noise level
+ * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
+ *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
+ *
+ * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
+ * 	has been changed and provides details of the request information
+ * 	that caused the change such as who initiated the regulatory request
+ * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
+ * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
+ * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
+ * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
+ * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
+ * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
+ * 	to (%NL80211_ATTR_REG_ALPHA2).
+ * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
+ * 	has been found while world roaming thus enabling active scan or
+ * 	any mode of operation that initiates TX (beacons) on a channel
+ * 	where we would not have been able to do either before. As an example
+ * 	if you are world roaming (regulatory domain set to world or if your
+ * 	driver is using a custom world roaming regulatory domain) and while
+ * 	doing a passive scan on the 5 GHz band you find an AP there (if not
+ * 	on a DFS channel) you will now be able to actively scan for that AP
+ * 	or use AP mode on your card on that same channel. Note that this will
+ * 	never be used for channels 1-11 on the 2 GHz band as they are always
+ * 	enabled world wide. This beacon hint is only sent if your device had
+ * 	either disabled active scanning or beaconing on a channel. We send to
+ * 	userspace the wiphy on which we removed a restriction from
+ * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
+ * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
+ * 	the beacon hint was processed.
+ *
+ * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
+ *	This command is used both as a command (request to authenticate) and
+ *	as an event on the "mlme" multicast group indicating completion of the
+ *	authentication process.
+ *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ *	the SSID (mainly for association, but is included in authentication
+ *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ *	to be added to the frame.
+ *	When used as an event, this reports reception of an Authentication
+ *	frame in station and IBSS modes when the local MLME processed the
+ *	frame, i.e., it was for the local STA and was received in correct
+ *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
+ *	MLME SAP interface (kernel providing MLME, userspace SME). The
+ *	included %NL80211_ATTR_FRAME attribute contains the management frame
+ *	(including both the header and frame body, but not FCS). This event is
+ *	also used to indicate if the authentication attempt timed out. In that
+ *	case the %NL80211_ATTR_FRAME attribute is replaced with a
+ *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
+ *	pending authentication timed out).
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
+ *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
+ *	primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
+ *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
+ *
+ * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
+ *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
+ *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
+ *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
+ *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
+ *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
+ *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
+ *
+ * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
+ *	FREQ attribute (for the initial frequency if no peer can be found)
+ *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
+ *	should be fixed rather than automatically determined. Can only be
+ *	executed on a network interface that is UP, and fixed BSSID/FREQ
+ *	may be rejected. Another optional parameter is the beacon interval,
+ *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
+ *	given defaults to 100 TU (102.4ms).
+ * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
+ *	determined by the network interface.
+ *
+ * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
+ *	to identify the device, and the TESTDATA blob attribute to pass through
+ *	to the driver.
+ *
+ * @NL80211_CMD_CONNECT: connection request and notification; this command
+ *	requests to connect to a specified network but without separating
+ *	auth and assoc steps. For this, you need to specify the SSID in a
+ *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
+ *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
+ *	%NL80211_ATTR_WIPHY_FREQ and %NL80211_ATTR_CONTROL_PORT.
+ *	It is also sent as an event, with the BSSID and response IEs when the
+ *	connection is established or failed to be established. This can be
+ *	determined by the STATUS_CODE attribute.
+ * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
+ *	sent as an event when the card/driver roamed by itself.
+ * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
+ *	userspace that a connection was dropped by the AP or due to other
+ *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
+ *	%NL80211_ATTR_REASON_CODE attributes are used.
+ *
+ * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
+ *	associated with this wiphy must be down and will follow.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ * NODEMASK_SCRATCH
+ * When doing above logical AND, OR, XOR, Remap operations the callers tend to

+ * for such situations. See below and CPUMASK_ALLOC also.

+   chips.
+
+   The GPIO units on these chips have the same pin architecture, but

+   implement their own versions of these routines; and use the common
+   file-operations routines implemented in nsc_gpio module.

+ * PG_highmem pages are not permanently mapped into the kernel virtual address
+ * space, they need to be kmapped separately for doing IO on the pages.  The
+ * struct page (these bits with information) are always mapped into kernel
+ * address space...

+ * (see mm/page_alloc.c).

+ * B. remove page from pagecache

+ * - A runs before 2: in this case, 2 sees zero refcount and retries;
+ *   subsequently, B will complete and 1 will find no page, causing the
+ *   lookup to return NULL.
+ *
+ * It is possible that between 1 and 2, the page is removed then the exact same
+ * page is inserted into the same position in pagecache. That's OK: the
+ * old find_get_page using tree_lock could equally have run before or after
+ * such a re-insertion, depending on order that locks are granted.
+ *

+/* 	pg.h (c) 1998  Grant R. Guenther <grant@torque.net>
+ 		       Under the terms of the GNU General Public License
+
+
+	pg.h defines the user interface to the generic ATAPI packet
+        command driver for parallel port ATAPI devices (pg). The
+	driver is loosely modelled after the generic SCSI driver, sg,
+	although the actual interface is different.
+
+	The pg driver provides a simple character device interface for
+        sending ATAPI commands to a device.  With the exception of the
+	ATAPI reset operation, all operations are performed by a pair
+        of read and write operations to the appropriate /dev/pgN device.
+	A write operation delivers a command and any outbound data in
+        a single buffer.  Normally, the write will succeed unless the
+        device is offline or malfunctioning, or there is already another
+	command pending.  If the write succeeds, it should be followed
+        immediately by a read operation, to obtain any returned data and
+        status information.  A read will fail if there is no operation
+        in progress.
+
+	As a special case, the device can be reset with a write operation,
+        and in this case, no following read is expected, or permitted.
+
+	There are no ioctl() operations.  Any single operation
+	may transfer at most PG_MAX_DATA bytes.  Note that the driver must
+        copy the data through an internal buffer.  In keeping with all
+	current ATAPI devices, command packets are assumed to be exactly
+	12 bytes in length.
+
+	To permit future changes to this interface, the headers in the
+	read and write buffers contain a single character "magic" flag.
+        Currently this flag must be the character "P".

+ * - If autonegotiation finishes, but there's no link, it sets

+ * - If aneg finishes with link, it sets the state to RUNNING,

+ * - If autonegotiation did not finish after an arbitrary amount
+ *   of time, autonegotiation should be tried again if the PHY
+ *   supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.
+ *
+ * NOLINK: PHY is up, but not currently plugged in.
+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN

+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and

+ * - phy_stop moves to HALTED
+ *
+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ *   link state is polled every other cycle of this state machine,
+ *   which makes it every other second)
+ * - irq will set CHANGELINK

+ * What is struct pid?
+ *
+ * A struct pid is the kernel's internal notion of a process identifier.
+ * It refers to individual tasks, process groups, and sessions.  While
+ * there are processes attached to it the struct pid lives in a hash
+ * table, so it and then the processes that it refers to can be found
+ * quickly from the numeric pid value.  The attached processes may be
+ * quickly accessed by following pointers from struct pid.
+ *
+ * Storing pid_t values in the kernel and refering to them later has a
+ * problem.  The process originally with that pid may have exited and the
+ * pid allocator wrapped, and another process could have come along
+ * and been assigned that pid.
+ *
+ * Referring to user space processes by holding a reference to struct
+ * task_struct has a problem.  When the user space process exits
+ * the now useless task_struct is still kept.  A task_struct plus a
+ * stack consumes around 10K of low kernel memory.  More precisely
+ * this is THREAD_SIZE + sizeof(struct task_struct).  By comparison
+ * a struct pid is about 64 bytes.
+ *
+ * Holding a reference to struct pid solves both of these problems.
+ * It is small so holding a reference does not consume a lot of
+ * resources, and since a new struct pid is allocated when the numeric pid
+ * value is reused (when pids wrap around) we don't mistakenly refer to new

+ *
+ * Licensed under the FSF's GNU Public License v2 or later.
+ *
+ * Based on simple lists (include/linux/list.h).
+ *
+ * This is a priority-sorted list of nodes; each node has a
+ * priority from INT_MIN (highest) to INT_MAX (lowest).
+ *
+ * Addition is O(K), removal is O(1), change of priority of a node is
+ * O(K) and K is the number of RT priority levels used in the system.
+ * (1 <= K <= 99)
+ *
+ * This list is really a list of lists:
+ *
+ *  - The tier 1 list is the prio_list, different priority nodes.
+ *
+ *  - The tier 2 list is the node_list, serialized nodes.
+ *
+ * Simple ASCII art explanation:
+ *
+ * |HEAD          |
+ * |              |
+ * |prio_list.prev|<------------------------------------|
+ * |prio_list.next|<->|pl|<->|pl|<--------------->|pl|<-|
+ * |10            |   |10|   |21|   |21|   |21|   |40|   (prio)
+ * |              |   |  |   |  |   |  |   |  |   |  |
+ * |              |   |  |   |  |   |  |   |  |   |  |
+ * |node_list.next|<->|nl|<->|nl|<->|nl|<->|nl|<->|nl|<-|
+ * |node_list.prev|<------------------------------------|
+ *
+ * The nodes on the prio_list list are sorted by priority to simplify
+ * the insertion of new nodes. There are no nodes with duplicate
+ * priorites on the list.
+ *
+ * The nodes on the node_list is ordered by priority and can contain
+ * entries which have the same priority. Those entries are ordered
+ * FIFO
+ *
+ * Addition means: look for the prio_list node in the prio_list
+ * for the priority of the node and insert it before the node_list
+ * entry of the next prio_list node. If it is the first node of
+ * that priority, add it to the prio_list in the right position and
+ * insert it into the serialized node_list list
+ *
+ * Removal means remove it from the node_list and remove it from
+ * the prio_list if the node_list list_head is non empty. In case
+ * of removal from the prio_list it must be checked whether other
+ * entries of the same priority are on the list or not. If there
+ * is another entry of the same priority then this entry has to
+ * replace the removed entry on the prio_list. If the entry which
+ * is removed is the only entry of this priority then a simple
+ * remove from both list is sufficient.
+ *
+ * INT_MIN is the highest priority, 0 is the medium highest, INT_MAX
+ * is lowest priority.
+ *
+ * No locking is done, up to the caller.

+/**
+ * struct dev_pm_ops - device PM callbacks
+ *
+ * Several driver power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state.  There may also be
+ * internal transitions to various low power modes, which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
+ *
+ * The externally visible transitions are handled with the help of the following
+ * callbacks included in this structure:
+ *
+ * @prepare: Prepare the device for the upcoming transition, but do NOT change
+ *	its hardware state.  Prevent new children of the device from being
+ *	registered after @prepare() returns (the driver's subsystem and
+ *	generally the rest of the kernel is supposed to prevent new calls to the
+ *	probe method from being made too once @prepare() has succeeded).  If
+ *	@prepare() detects a situation it cannot handle (e.g. registration of a
+ *	child already in progress), it may return -EAGAIN, so that the PM core
+ *	can execute it once again (e.g. after the new child has been registered)
+ *	to recover from the race condition.  This method is executed for all
+ *	kinds of suspend transitions and is followed by one of the suspend
+ *	callbacks: @suspend(), @freeze(), or @poweroff().
+ *	The PM core executes @prepare() for all devices before starting to
+ *	execute suspend callbacks for any of them, so drivers may assume all of
+ *	the other devices to be present and functional while @prepare() is being
+ *	executed.  In particular, it is safe to make GFP_KERNEL memory
+ *	allocations from within @prepare().  However, drivers may NOT assume
+ *	anything about the availability of the user space at that time and it
+ *	is not correct to request firmware from within @prepare() (it's too
+ *	late to do that).  [To work around this limitation, drivers may
+ *	register suspend and hibernation notifiers that are executed before the
+ *	freezing of tasks.]
+ *
+ * @complete: Undo the changes made by @prepare().  This method is executed for
+ *	all kinds of resume transitions, following one of the resume callbacks:
+ *	@resume(), @thaw(), @restore().  Also called if the state transition
+ *	fails before the driver's suspend callback (@suspend(), @freeze(),
+ *	@poweroff()) can be executed (e.g. if the suspend callback fails for one
+ *	of the other devices that the PM core has unsuccessfully attempted to
+ *	suspend earlier).
+ *	The PM core executes @complete() after it has executed the appropriate
+ *	resume callback for all devices.
+ *
+ * @suspend: Executed before putting the system into a sleep state in which the
+ *	contents of main memory are preserved.  Quiesce the device, put it into
+ *	a low power state appropriate for the upcoming system state (such as
+ *	PCI_D3hot), and enable wakeup events as appropriate.
+ *
+ * @resume: Executed after waking the system up from a sleep state in which the
+ *	contents of main memory were preserved.  Put the device into the
+ *	appropriate state, according to the information saved in memory by the
+ *	preceding @suspend().  The driver starts working again, responding to
+ *	hardware events and software requests.  The hardware may have gone
+ *	through a power-off reset, or it may have maintained state from the
+ *	previous suspend() which the driver may rely on while resuming.  On most
+ *	platforms, there are no restrictions on availability of resources like
+ *	clocks during @resume().
+ *
+ * @freeze: Hibernation-specific, executed before creating a hibernation image.
+ *	Quiesce operations so that a consistent image can be created, but do NOT
+ *	otherwise put the device into a low power device state and do NOT emit
+ *	system wakeup events.  Save in main memory the device settings to be
+ *	used by @restore() during the subsequent resume from hibernation or by
+ *	the subsequent @thaw(), if the creation of the image or the restoration
+ *	of main memory contents from it fails.
+ *
+ * @thaw: Hibernation-specific, executed after creating a hibernation image OR
+ *	if the creation of the image fails.  Also executed after a failing
+ *	attempt to restore the contents of main memory from such an image.
+ *	Undo the changes made by the preceding @freeze(), so the device can be
+ *	operated in the same way as immediately before the call to @freeze().
+ *
+ * @poweroff: Hibernation-specific, executed after saving a hibernation image.
+ *	Quiesce the device, put it into a low power state appropriate for the
+ *	upcoming system state (such as PCI_D3hot), and enable wakeup events as
+ *	appropriate.
+ *
+ * @restore: Hibernation-specific, executed after restoring the contents of main
+ *	memory from a hibernation image.  Driver starts working again,
+ *	responding to hardware events and software requests.  Drivers may NOT
+ *	make ANY assumptions about the hardware state right prior to @restore().
+ *	On most platforms, there are no restrictions on availability of
+ *	resources like clocks during @restore().
+ *
+ * @suspend_noirq: Complete the operations of ->suspend() by carrying out any
+ *	actions required for suspending the device that need interrupts to be
+ *	disabled
+ *
+ * @resume_noirq: Prepare for the execution of ->resume() by carrying out any
+ *	actions required for resuming the device that need interrupts to be
+ *	disabled
+ *
+ * @freeze_noirq: Complete the operations of ->freeze() by carrying out any
+ *	actions required for freezing the device that need interrupts to be
+ *	disabled
+ *
+ * @thaw_noirq: Prepare for the execution of ->thaw() by carrying out any
+ *	actions required for thawing the device that need interrupts to be
+ *	disabled
+ *
+ * @poweroff_noirq: Complete the operations of ->poweroff() by carrying out any
+ *	actions required for handling the device that need interrupts to be
+ *	disabled
+ *
+ * @restore_noirq: Prepare for the execution of ->restore() by carrying out any
+ *	actions required for restoring the operations of the device that need
+ *	interrupts to be disabled
+ *
+ * All of the above callbacks, except for @complete(), return error codes.
+ * However, the error codes returned by the resume operations, @resume(),
+ * @thaw(), @restore(), @resume_noirq(), @thaw_noirq(), and @restore_noirq() do
+ * not cause the PM core to abort the resume transition during which they are
+ * returned.  The error codes returned in that cases are only printed by the PM
+ * core to the system logs for debugging purposes.  Still, it is recommended
+ * that drivers only return error codes from their resume methods in case of an
+ * unrecoverable failure (i.e. when the device being handled refuses to resume
+ * and becomes unusable) to allow us to modify the PM core in the future, so
+ * that it can avoid attempting to handle devices that failed to resume and
+ * their children.
+ *
+ * It is allowed to unregister devices while the above callbacks are being
+ * executed.  However, it is not allowed to unregister a device from within any
+ * of its own callbacks.
+ *
+ * There also are the following callbacks related to run-time power management
+ * of devices:
+ *
+ * @runtime_suspend: Prepare the device for a condition in which it won't be
+ *	able to communicate with the CPU(s) and RAM due to power management.
+ *	This need not mean that the device should be put into a low power state.
+ *	For example, if the device is behind a link which is about to be turned
+ *	off, the device may remain at full power.  If the device does go to low
+ *	power and is capable of generating run-time wake-up events, remote
+ *	wake-up (i.e., a hardware mechanism allowing the device to request a
+ *	change of its power state via a wake-up event, such as PCI PME) should
+ *	be enabled for it.
+ *
+ * @runtime_resume: Put the device into the fully active state in response to a
+ *	wake-up event generated by hardware or at the request of software.  If
+ *	necessary, put the device into the full power state and restore its
+ *	registers, so that it is fully operational.
+ *
+ * @runtime_idle: Device appears to be inactive and it might be put into a low
+ *	power state if all of the necessary conditions are satisfied.  Check
+ *	these conditions and handle the device as appropriate, possibly queueing
+ *	a suspend request for it.  The return value is ignored by the PM core.

+/**
+ * Radix-tree synchronization
+ *
+ * The radix-tree API requires that users provide all synchronisation (with
+ * specific exceptions, noted below).
+ *
+ * Synchronization of access to the data items being stored in the tree, and
+ * management of their lifetimes must be completely managed by API users.
+ *
+ * For API usage, in general,
+ * - any function _modifying_ the tree or tags (inserting or deleting
+ *   items, setting or clearing tags) must exclude other modifications, and
+ *   exclude any functions reading the tree.
+ * - any function _reading_ the tree or tags (looking up items or tags,
+ *   gang lookups) must exclude modifications to the tree, but may occur
+ *   concurrently with other readers.
+ *
+ * The notable exceptions to this rule are the following functions:
+ * radix_tree_lookup
+ * radix_tree_lookup_slot
+ * radix_tree_tag_get
+ * radix_tree_gang_lookup
+ * radix_tree_gang_lookup_slot
+ * radix_tree_gang_lookup_tag
+ * radix_tree_gang_lookup_tag_slot
+ * radix_tree_tagged
+ *
+ * The first 7 functions are able to be called locklessly, using RCU. The
+ * caller must ensure calls to these functions are made within rcu_read_lock()
+ * regions. Other readers (lock-free or otherwise) and modifications may be
+ * running concurrently.
+ *
+ * It is still required that the caller manage the synchronization and lifetimes
+ * of the items. So if RCU lock-free lookups are used, typically this would mean
+ * that the items have their own locks, or are amenable to lock-free access; and
+ * that the items are freed by RCU (or only freed after having been deleted from
+ * the radix tree *and* a synchronize_rcu() grace period).
+ *
+ * (Note, rcu_assign_pointer and rcu_dereference are not needed to control
+ * access to data items when inserting into or looking up from the radix tree)
+ *
+ * radix_tree_tagged is able to be called without locking or RCU.

+  To use rbtrees you'll have to implement your own insert and search cores.
+  This will avoid us to use callbacks and to drop drammatically performances.
+  I know it's not the cleaner way,  but in C (not in C++) to get
+  performances and genericity...
+
+  Some example of insert and search follows here. The search is a plain
+  normal search over an ordered tree. The insert instead must be implemented
+  int two steps: as first thing the code must insert the element in
+  order as a red leaf in the tree, then the support library function
+  rb_insert_color() must be called. Such function will do the
+  not trivial work to rebalance the rbtree if necessary.

+ * CPUs exit their critical sections.  Similarly, if call_rcu() is invoked

+ * an RCU callback, (3) CPU 0 exits the RCU read-side critical section,
+ * (4) CPU 2 enters a RCU read-side critical section, (5) the RCU
+ * callback is invoked.  This is legal, because the RCU read-side critical
+ * section that was running concurrently with the call_rcu() (and which
+ * therefore might be referencing something that the corresponding RCU
+ * callback would free up) has completed before the corresponding
+ * RCU callback is invoked.

+ * RCU read-side critical sections may be nested.  Any deferred actions

+ * This data structure describes a machine resource we call a register set.

+ * similar slots, given by @n.  Each slot is @size bytes, and aligned to
+ * @align bytes (which is at least @size).
+ *
+ * These functions must be called only on the current thread or on a

+ *
+ * When there is a natural value to use as an index, @bias gives the
+ * difference between the natural index and the slot index for the
+ * register set.  For example, x86 GDT segment descriptors form a regset;

+ * that index space is available as a regset (the TLS slots); subtracting

+ *
+ * If nonzero, @core_note_type gives the n_type field (NT_* value)
+ * of the core file note in which this regset's data appears.
+ * NT_PRSTATUS is a special case in that the regset data starts at

+ * Regulator operating modes.
+ *
+ * Regulators can run in a variety of different operating modes depending on
+ * output load. This allows further system power savings by selecting the
+ * best (and most efficient) regulator mode for a desired load.
+ *
+ * Most drivers will only care about NORMAL. The modes below are generic and
+ * will probably not match the naming convention of your regulator data sheet
+ * but should match the use cases in the datasheet.
+ *
+ * In order of power efficiency (least efficient at top).
+ *
+ *  Mode       Description
+ *  FAST       Regulator can handle fast changes in it's load.
+ *             e.g. useful in CPU voltage & frequency scaling where
+ *             load can quickly increase with CPU frequency increases.
+ *
+ *  NORMAL     Normal regulator power supply mode. Most drivers will
+ *             use this mode.
+ *
+ *  IDLE       Regulator runs in a more efficient mode for light
+ *             loads. Can be used for devices that have a low power
+ *             requirement during periods of inactivity. This mode
+ *             may be more noisy than NORMAL and may not be able
+ *             to handle fast load switching.
+ *
+ *  STANDBY    Regulator runs in the most efficient mode for very
+ *             light loads. Can be used by devices when they are
+ *             in a sleep/standby state. This mode is likely to be
+ *             the most noisy and may not be able to handle fast load
+ *             switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
+ * These modes can be OR'ed together to make up a mask of valid register modes.

+/* LOGGING -- */
+
+/* These all interelate for performance.
+**
+** If the journal block count is smaller than n transactions, you lose speed.
+** I don't know what n is yet, I'm guessing 8-16.
+**
+** typical transaction size depends on the application, how often fsync is
+** called, and how many metadata blocks you dirty in a 30 second period.
+** The more small files (<16k) you use, the larger your transactions will
+** be.
+**
+** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
+** to wrap, which slows things down.  If you need high speed meta data updates, the journal should be big enough
+** to prevent wrapping before dirty meta blocks get to disk.
+**
+** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
+** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
+**
+** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.

+ * struct security_operations - main security structure
+ *
+ * Security module identifier.
+ *
+ * @name:
+ *	A string that acts as a unique identifeir for the LSM with max number
+ *	of characters = SECURITY_NAME_MAX.
+ *
+ * Security hooks for program execution operations.
+ *
+ * @bprm_set_creds:
+ *	Save security information in the bprm->security field, typically based
+ *	on information about the bprm->file, for later use by the apply_creds
+ *	hook.  This hook may also optionally check permissions (e.g. for
+ *	transitions between security domains).
+ *	This hook may be called multiple times during a single execve, e.g. for
+ *	interpreters.  The hook can tell whether it has already been called by
+ *	checking to see if @bprm->security is non-NULL.  If so, then the hook
+ *	may decide either to retain the security information saved earlier or
+ *	to replace it.
+ *	@bprm contains the linux_binprm structure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @bprm_check_security:
+ *	This hook mediates the point when a search for a binary handler will
+ *	begin.  It allows a check the @bprm->security value which is set in the
+ *	preceding set_creds call.  The primary difference from set_creds is
+ *	that the argv list and envp list are reliably available in @bprm.  This
+ *	hook may be called multiple times during a single execve; and in each
+ *	pass set_creds is called first.
+ *	@bprm contains the linux_binprm structure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @bprm_committing_creds:
+ *	Prepare to install the new security attributes of a process being
+ *	transformed by an execve operation, based on the old credentials
+ *	pointed to by @current->cred and the information set in @bprm->cred by
+ *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
+ *	This hook is a good place to perform state changes on the process such
+ *	as closing open file descriptors to which access will no longer be
+ *	granted when the attributes are changed.  This is called immediately
+ *	before commit_creds().
+ * @bprm_committed_creds:
+ *	Tidy up after the installation of the new security attributes of a
+ *	process being transformed by an execve operation.  The new credentials
+ *	have, by this point, been set to @current->cred.  @bprm points to the
+ *	linux_binprm structure.  This hook is a good place to perform state
+ *	changes on the process such as clearing out non-inheritable signal
+ *	state.  This is called immediately after commit_creds().
+ * @bprm_secureexec:
+ *	Return a boolean value (0 or 1) indicating whether a "secure exec"
+ *	is required.  The flag is passed in the auxiliary table
+ *	on the initial stack to the ELF interpreter to indicate whether libc
+ *	should enable secure mode.
+ *	@bprm contains the linux_binprm structure.
+ *
+ * Security hooks for filesystem operations.
+ *
+ * @sb_alloc_security:
+ *	Allocate and attach a security structure to the sb->s_security field.
+ *	The s_security field is initialized to NULL when the structure is
+ *	allocated.
+ *	@sb contains the super_block structure to be modified.
+ *	Return 0 if operation was successful.
+ * @sb_free_security:
+ *	Deallocate and clear the sb->s_security field.
+ *	@sb contains the super_block structure to be modified.
+ * @sb_statfs:
+ *	Check permission before obtaining filesystem statistics for the @mnt
+ *	mountpoint.
+ *	@dentry is a handle on the superblock for the filesystem.
+ *	Return 0 if permission is granted.
+ * @sb_mount:
+ *	Check permission before an object specified by @dev_name is mounted on
+ *	the mount point named by @nd.  For an ordinary mount, @dev_name
+ *	identifies a device if the file system type requires a device.  For a
+ *	remount (@flags & MS_REMOUNT), @dev_name is irrelevant.  For a
+ *	loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
+ *	pathname of the object being mounted.
+ *	@dev_name contains the name for object being mounted.
+ *	@path contains the path for mount point object.
+ *	@type contains the filesystem type.
+ *	@flags contains the mount flags.
+ *	@data contains the filesystem-specific data.

+ *	@field contains the required Audit action. Fields flags are defined in include/linux/audit.h
+ *	@op contains the operator the rule uses.
+ *	@rulestr contains the context where the rule will be applied to.
+ *	@lsmrule contains a pointer to receive the result.
+ *	Return 0 if @lsmrule has been successfully set,
+ *	-EINVAL in case of an invalid rule.
+ *
+ * @audit_rule_known:
+ *	Specifies whether given @rule contains any fields related to current LSM.
+ *	@rule contains the audit rule of interest.
+ *	Return 1 in case of relation found, 0 otherwise.
+ *
+ * @audit_rule_match:
+ *	Determine if given @secid matches a rule previously approved
+ *	by @audit_rule_known.
+ *	@secid contains the security id in question.
+ *	@field contains the field which relates to current LSM.
+ *	@op contains the operator that will be used for matching.
+ *	@rule points to the audit rule that will be checked against.
+ *	@actx points to the audit context associated with the check.
+ *	Return 1 if secid matches the rule, 0 if it does not, -ERRNO on failure.
+ *
+ * @audit_rule_free:
+ *	Deallocate the LSM audit rule structure previously allocated by
+ *	audit_rule_init.
+ *	@rule contains the allocated rule
+ *
+ * @inode_notifysecctx:
+ *	Notify the security module of what the security context of an inode
+ *	should be.  Initializes the incore security context managed by the
+ *	security module for this inode.  Example usage:  NFS client invokes
+ *	this hook to initialize the security context in its incore inode to the
+ *	value provided by the server for the file when the server returned the
+ *	file's attributes to the client.
+ *
+ * 	Must be called with inode->i_mutex locked.
+ *
+ * 	@inode we wish to set the security context of.
+ * 	@ctx contains the string which we wish to set in the inode.
+ * 	@ctxlen contains the length of @ctx.
+ *
+ * @inode_setsecctx:
+ * 	Change the security context of an inode.  Updates the
+ * 	incore security context managed by the security module and invokes the
+ * 	fs code as needed (via __vfs_setxattr_noperm) to update any backing
+ * 	xattrs that represent the context.  Example usage:  NFS server invokes
+ * 	this hook to change the security context in its incore inode and on the
+ * 	backing filesystem to a value provided by the client on a SETATTR
+ * 	operation.
+ *
+ * 	Must be called with inode->i_mutex locked.
+ *
+ * 	@dentry contains the inode we wish to set the security context of.
+ * 	@ctx contains the string which we wish to set in the inode.
+ * 	@ctxlen contains the length of @ctx.
+ *
+ * @inode_getsecctx:
+ * 	Returns a string containing all relavent security context information
+ *
+ * 	@inode we wish to set the security context of.
+ *	@ctx is a pointer in which to place the allocated security context.
+ *	@ctxlen points to the place to put the length of @ctx.
+ * This is the main security structure.

+ * In POSIX a signal is sent either to a specific thread (Linux task)
+ * or to the process as a whole (Linux thread group).  How the signal
+ * is sent determines whether it's to one thread or the whole group,
+ * which determines which signal mask(s) are involved in blocking it
+ * from being delivered until later.  When the signal is delivered,
+ * either it's caught or ignored by a user handler or it has a default
+ * effect that applies to the whole thread group (POSIX process).
+ *
+ * The possible effects an unblocked signal set to SIG_DFL can have are:
+ *   ignore	- Nothing Happens
+ *   terminate	- kill the process, i.e. all threads in the group,
+ * 		  similar to exit_group.  The group leader (only) reports
+ *		  WIFSIGNALED status to its parent.
+ *   coredump	- write a core dump file describing all threads using
+ *		  the same mm and then kill all those threads
+ *   stop 	- stop all the threads in the group, i.e. TASK_STOPPED state
+ *
+ * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
+ * Other signals when not blocked and set to SIG_DFL behaves as follows.
+ * The job control signals also have other special effects.

+ * B. Checksumming on output.
+ *
+ *	NONE: skb is checksummed by protocol or csum is not required.
+ *
+ *	PARTIAL: device is required to csum packet as seen by hard_start_xmit

+ *	at skb->csum_start + skb->csum_offset.
+ *
+ *	Device must show its capabilities in dev->features, set

+ *	NETIF_F_HW_CSUM	- it is clever device, it is able to checksum
+ *			  everything.
+ *	NETIF_F_NO_CSUM - loopback or reliable single hop media.
+ *	NETIF_F_IP_CSUM - device is dumb. It is able to csum only
+ *			  TCP/UDP over IPv4. Sigh. Vendors like this
+ *			  way by an unknown reason. Though, see comment above
+ *			  about CHECKSUM_UNNECESSARY. 8)

+ *

+ * up to the protocol driver, which guarantees the integrity of both (as
+ * well as the data buffers) for as long as the message is queued.
+ */
+
+/**
+ * struct spi_transfer - a read/write buffer pair
+ * @tx_buf: data to be written (dma-safe memory), or NULL
+ * @rx_buf: data to be read (dma-safe memory), or NULL
+ * @tx_dma: DMA address of tx_buf, if @spi_message.is_dma_mapped
+ * @rx_dma: DMA address of rx_buf, if @spi_message.is_dma_mapped
+ * @len: size of rx and tx buffers (in bytes)
+ * @speed_hz: Select a speed other than the device default for this
+ *      transfer. If 0 the default (from @spi_device) is used.
+ * @bits_per_word: select a bits_per_word other than the device default
+ *      for this transfer. If 0 the default (from @spi_device) is used.
+ * @cs_change: affects chipselect after this transfer completes
+ * @delay_usecs: microseconds to delay after this transfer before
+ *	(optionally) changing the chipselect status, then starting
+ *	the next transfer or completing this @spi_message.
+ * @transfer_list: transfers are sequenced through @spi_message.transfers
+ *
+ * SPI transfers always write the same number of bytes as they read.
+ * Protocol drivers should always provide @rx_buf and/or @tx_buf.
+ * In some cases, they may also want to provide DMA addresses for
+ * the data being transferred; that may reduce overhead, when the
+ * underlying driver uses dma.
+ *
+ * If the transmit buffer is null, zeroes will be shifted out
+ * while filling @rx_buf.  If the receive buffer is null, the data
+ * shifted in will be discarded.  Only "len" bytes shift out (or in).
+ * It's an error to try to shift out a partial word.  (For example, by
+ * shifting out three bytes with word size of sixteen or twenty bits;
+ * the former uses two bytes per word, the latter uses four bytes.)
+ *
+ * In-memory data values are always in native CPU byte order, translated
+ * from the wire byte order (big-endian except with SPI_LSB_FIRST).  So
+ * for example when bits_per_word is sixteen, buffers are 2N bytes long
+ * (@len = 2N) and hold N sixteen bit words in CPU byte order.
+ *
+ * When the word size of the SPI transfer is not a power-of-two multiple
+ * of eight bits, those in-memory words include extra bits.  In-memory
+ * words are always seen by protocol drivers as right-justified, so the
+ * undefined (rx) or unused (tx) bits are always the most significant bits.
+ *
+ * All SPI transfers start with the relevant chipselect active.  Normally
+ * it stays selected until after the last transfer in a message.  Drivers
+ * can affect the chipselect signal using cs_change.
+ *
+ * (i) If the transfer isn't the last one in the message, this flag is
+ * used to make the chipselect briefly go inactive in the middle of the
+ * message.  Toggling chipselect in this way may be needed to terminate
+ * a chip command, letting a single spi_message perform all of group of
+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer.  On multi-device SPI busses
+ * with nothing blocking messages going to other devices, this is just
+ * a performance hint; starting a message to another device deselects
+ * this one.  But in other cases, this can be used to ensure correctness.
+ * Some devices need protocol transactions to be built from a series of
+ * spi_message submissions, where the content of one message is determined
+ * by the results of previous messages and where the whole transaction
+ * ends when the chipselect goes intactive.
+ *
+ * The code that submits an spi_message (and its spi_transfers)
+ * to the lower layers is responsible for managing its memory.
+ * Zero-initialize every field you don't set up explicitly, to
+ * insulate against future API updates.  After you submit a message
+ * and its transfers, ignore them until its completion callback.

+ *	h1.h2.h3.h4.p1.p2
+ *
+ * The prefix, "h1.h2.h3.h4", is the standard textual form for
+ * representing an IPv4 address, which is always four octets long.
+ * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
+ * the first through fourth octets each converted to ASCII-decimal.
+ * Assuming big-endian ordering, p1 and p2 are, respectively, the first
+ * and second octets each converted to ASCII-decimal.  For example, if a
+ * host, in big-endian order, has an address of 0x0A010307 and there is
+ * a service listening on, in big endian order, port 0x020F (decimal
+ * 527), then the complete universal address is "10.1.3.7.2.15".
+ *
+ * ...
+ *
+ * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
+ * US-ASCII string:
+ *
+ *	x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
+ *
+ * The suffix "p1.p2" is the service port, and is computed the same way
+ * as with universal addresses for TCP and UDP over IPv4.  The prefix,
+ * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
+ * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
+ * Additionally, the two alternative forms specified in Section 2.2 of
+ * [RFC2373] are also acceptable.

+ * struct platform_suspend_ops - Callbacks for managing platform dependent
+ *	system sleep states.
+ *
+ * @valid: Callback to determine if given system sleep state is supported by
+ *	the platform.
+ *	Valid (ie. supported) states are advertised in /sys/power/state.  Note
+ *	that it still may be impossible to enter given system sleep state if the
+ *	conditions aren't right.
+ *	There is the %suspend_valid_only_mem function available that can be
+ *	assigned to this if the platform only supports mem sleep.
+ *
+ * @begin: Initialise a transition to given system sleep state.
+ *	@begin() is executed right prior to suspending devices.  The information
+ *	conveyed to the platform code by @begin() should be disregarded by it as
+ *	soon as @end() is executed.  If @begin() fails (ie. returns nonzero),
+ *	@prepare(), @enter() and @finish() will not be called by the PM core.
+ *	This callback is optional.  However, if it is implemented, the argument
+ *	passed to @enter() is redundant and should be ignored.
+ *
+ * @prepare: Prepare the platform for entering the system sleep state indicated
+ *	by @begin().
+ *	@prepare() is called right after devices have been suspended (ie. the
+ *	appropriate .suspend() method has been executed for each device) and
+ *	before device drivers' late suspend callbacks are executed.  It returns
+ *	0 on success or a negative error code otherwise, in which case the
+ *	system cannot enter the desired sleep state (@prepare_late(), @enter(),
+ *	@wake(), and @finish() will not be called in that case).
+ *
+ * @prepare_late: Finish preparing the platform for entering the system sleep
+ *	state indicated by @begin().
+ *	@prepare_late is called before disabling nonboot CPUs and after
+ *	device drivers' late suspend callbacks have been executed.  It returns
+ *	0 on success or a negative error code otherwise, in which case the
+ *	system cannot enter the desired sleep state (@enter() and @wake()).
+ *
+ * @enter: Enter the system sleep state indicated by @begin() or represented by
+ *	the argument if @begin() is not implemented.
+ *	This callback is mandatory.  It returns 0 on success or a negative
+ *	error code otherwise, in which case the system cannot enter the desired
+ *	sleep state.
+ *
+ * @wake: Called when the system has just left a sleep state, right after
+ *	the nonboot CPUs have been enabled and before device drivers' early
+ *	resume callbacks are executed.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @prepare_late().  If implemented, it is always called
+ *	after @enter(), even if @enter() fails.
+ *
+ * @finish: Finish wake-up of the platform.
+ *	@finish is called right prior to calling device drivers' regular suspend
+ *	callbacks.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @prepare().  If implemented, it is always called after
+ *	@enter() and @wake(), if implemented, even if any of them fails.
+ *
+ * @end: Called by the PM core right after resuming devices, to indicate to
+ *	the platform that the system has returned to the working state or
+ *	the transition to the sleep state has been aborted.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @begin().  Accordingly, platforms implementing @begin()
+ *	should also provide a @end() which cleans up transitions aborted before
+ *	@enter().
+ *
+ * @recover: Recover the platform from a suspend failure.
+ *	Called by the PM core if the suspending of devices fails.
+ *	This callback is optional and should only be implemented by platforms
+ *	which require special recovery actions in that situation.

+ * Utility code which helps transforming between two different time
+ * bases, called "source" and "target" time in this code.
+ *
+ * Source time has to be provided via the timecounter API while target
+ * time is accessed via a function callback whose prototype
+ * intentionally matches ktime_get() and ktime_get_real(). These
+ * interfaces where chosen like this so that the code serves its
+ * initial purpose without additional glue code.
+ *
+ * This purpose is synchronizing a hardware clock in a NIC with system
+ * time, in order to implement the Precision Time Protocol (PTP,
+ * IEEE1588) with more accurate hardware assisted time stamping.  In
+ * that context only synchronization against system time (=
+ * ktime_get_real()) is currently needed. But this utility code might
+ * become useful in other situations, which is why it was written as
+ * general purpose utility code.
+ *
+ * The source timecounter is assumed to return monotonically
+ * increasing time (but this code does its best to compensate if that
+ * is not the case) whereas target time may jump.
+ *
+ * The target time corresponding to a source time is determined by
+ * reading target time, reading source time, reading target time
+ * again, then assuming that average target time corresponds to source
+ * time. In other words, the assumption is that reading the source
+ * time is slow and involves equal time for sending the request and
+ * receiving the reply, whereas reading target time is assumed to be
+ * fast.

+ * This file defines hook entry points called by core code where
+ * user tracing/debugging support might need to do something.  These
+ * entry points are called tracehook_*().  Each hook declared below
+ * has a detailed kerneldoc comment giving the context (locking et
+ * al) from which it is called, and the meaning of its return value.
+ *
+ * Each function here typically has only one call site, so it is ok
+ * to have some nontrivial tracehook_*() inlines.  In all cases, the
+ * fast path when no tracing is enabled should be very short.
+ *
+ * The purpose of this file and the tracehook_* layer is to consolidate
+ * the interface that the kernel core and arch code uses to enable any
+ * user debugging or tracing facility (such as ptrace).  The interfaces
+ * here are carefully documented so that maintainers of core and arch
+ * code do not need to think about the implementation details of the
+ * tracing facilities.  Likewise, maintainers of the tracing code do not
+ * need to understand all the calling core or arch code in detail, just
+ * documented circumstances of each call, such as locking conditions.
+ *
+ * If the calling core code changes so that locking is different, then
+ * it is ok to change the interface documented here.  The maintainer of
+ * core code changing should notify the maintainers of the tracing code
+ * that they need to work out the change.
+ *
+ * Some tracehook_*() inlines take arguments that the current tracing
+ * implementations might not necessarily use.  These function signatures
+ * are chosen to pass in all the information that is on hand in the
+ * caller and might conceivably be relevant to a tracer, so that the
+ * core code won't have to be updated when tracing adds more features.
+ * If a call site changes so that some of those parameters are no longer
+ * already on hand without extra work, then the tracehook_* interface
+ * can change so there is no make-work burden on the core code.  The
+ * maintainer of core code changing should notify the maintainers of the
+ * tracing code that they need to work out the change.

+ *	* can refer to the trace record as '__entry' -

+ *	*
+ *	* Formatted output of a trace record via TP_printk().
+ *	* This is how the tracepoint will appear under ftrace

+ *
+ *	Optional method. Default behaviour is to use the ttys array
+ *
+ * void (*remove)(struct tty_driver *self, struct tty_struct *tty)
+ *
+ *	Remove a closed tty from the tty driver internal tables. Used in
+ *	conjunction with lookup and remove methods.
+ *
+ *	Optional method. Default behaviour is to use the ttys array
+ *
+ * int  (*open)(struct tty_struct * tty, struct file * filp);
+ *
+ * 	This routine is called when a particular tty device is opened.
+ * 	This routine is mandatory; if this routine is not filled in,
+ * 	the attempted open will fail with ENODEV.
+ *
+ *	Required method.
+ *     
+ * void (*close)(struct tty_struct * tty, struct file * filp);
+ *
+ * 	This routine is called when a particular tty device is closed.
+ *
+ *	Required method.
+ *
+ * void (*shutdown)(struct tty_struct * tty);
+ *
+ * 	This routine is called synchronously when a particular tty device
+ *	is closed for the last time freeing up the resources.
+ *
+ *
+ * void (*cleanup)(struct tty_struct * tty);
+ *
+ *	This routine is called asynchronously when a particular tty device
+ *	is closed for the last time freeing up the resources. This is
+ *	actually the second part of shutdown for routines that might sleep.
+ *
+ *
+ * int (*write)(struct tty_struct * tty,
+ * 		 const unsigned char *buf, int count);
+ *
+ * 	This routine is called by the kernel to write a series of
+ * 	characters to the tty device.  The characters may come from
+ * 	user space or kernel space.  This routine will return the
+ *	number of characters actually accepted for writing.
+ *
+ *	Optional: Required for writable devices.
+ *
+ * int (*put_char)(struct tty_struct *tty, unsigned char ch);
+ *
+ * 	This routine is called by the kernel to write a single
+ * 	character to the tty device.  If the kernel uses this routine,
+ * 	it must call the flush_chars() routine (if defined) when it is
+ * 	done stuffing characters into the driver.  If there is no room
+ * 	in the queue, the character is ignored.
+ *
+ *	Optional: Kernel will use the write method if not provided.
+ *
+ *	Note: Do not call this function directly, call tty_put_char
+ *
+ * void (*flush_chars)(struct tty_struct *tty);
+ *
+ * 	This routine is called by the kernel after it has written a
+ * 	series of characters to the tty device using put_char().  
+ *
+ *	Optional:
+ *
+ *	Note: Do not call this function directly, call tty_driver_flush_chars
+ * 
+ * int  (*write_room)(struct tty_struct *tty);
+ *
+ * 	This routine returns the numbers of characters the tty driver
+ * 	will accept for queuing to be written.  This number is subject
+ * 	to change as output buffers get emptied, or if the output flow
+ *	control is acted.
+ *
+ *	Required if write method is provided else not needed.
+ *
+ *	Note: Do not call this function directly, call tty_write_room
+ * 
+ * int  (*ioctl)(struct tty_struct *tty, struct file * file,
+ * 	    unsigned int cmd, unsigned long arg);
+ *
+ * 	This routine allows the tty driver to implement
+ *	device-specific ioctl's.  If the ioctl number passed in cmd
+ * 	is not recognized by the driver, it should return ENOIOCTLCMD.
+ *
+ *	Optional
+ *
+ * long (*compat_ioctl)(struct tty_struct *tty, struct file * file,
+ * 	                unsigned int cmd, unsigned long arg);
+ *
+ * 	implement ioctl processing for 32 bit process on 64 bit system
+ *
+ *	Optional
+ * 
+ * void (*set_termios)(struct tty_struct *tty, struct ktermios * old);
+ *
+ * 	This routine allows the tty driver to be notified when
+ * 	device's termios settings have changed.
+ *
+ *	Optional: Called under the termios lock
+ *
+ *
+ * void (*set_ldisc)(struct tty_struct *tty);
+ *
+ * 	This routine allows the tty driver to be notified when the
+ * 	device's termios settings have changed.
+ *
+ *	Optional: Called under BKL (currently)
+ * 
+ * void (*throttle)(struct tty_struct * tty);
+ *
+ * 	This routine notifies the tty driver that input buffers for
+ * 	the line discipline are close to full, and it should somehow
+ * 	signal that no more characters should be sent to the tty.
+ *
+ *	Optional: Always invoke via tty_throttle(), called under the
+ *	termios lock.
+ * 
+ * void (*unthrottle)(struct tty_struct * tty);
+ *
+ * 	This routine notifies the tty drivers that it should signals
+ * 	that characters can now be sent to the tty without fear of
+ * 	overrunning the input buffers of the line disciplines.
+ * 
+ *	Optional: Always invoke via tty_unthrottle(), called under the
+ *	termios lock.
+ *
+ * void (*stop)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it should stop
+ * 	outputting characters to the tty device.  
+ *
+ *	Optional:
+ *
+ *	Note: Call stop_tty not this method.
+ * 
+ * void (*start)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it resume sending
+ *	characters to the tty device.
+ *
+ *	Optional:
+ *
+ *	Note: Call start_tty not this method.
+ * 
+ * void (*hangup)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it should hangup the
+ * 	tty device.
+ *
+ *	Optional:
+ *
+ * int (*break_ctl)(struct tty_stuct *tty, int state);
+ *
+ * 	This optional routine requests the tty driver to turn on or
+ * 	off BREAK status on the RS-232 port.  If state is -1,
+ * 	then the BREAK status should be turned on; if state is 0, then
+ * 	BREAK should be turned off.
+ *
+ * 	If this routine is implemented, the high-level tty driver will
+ * 	handle the following ioctls: TCSBRK, TCSBRKP, TIOCSBRK,
+ * 	TIOCCBRK.
+ *
+ *	If the driver sets TTY_DRIVER_HARDWARE_BREAK then the interface
+ *	will also be called with actual times and the hardware is expected
+ *	to do the delay work itself. 0 and -1 are still used for on/off.
+ *
+ *	Optional: Required for TCSBRK/BRKP/etc handling.
+ *
+ * void (*wait_until_sent)(struct tty_struct *tty, int timeout);
+ * 
+ * 	This routine waits until the device has written out all of the
+ * 	characters in its transmitter FIFO.
+ *
+ *	Optional: If not provided the device is assumed to have no FIFO
+ *
+ *	Note: Usually correct to call tty_wait_until_sent
+ *
+ * void (*send_xchar)(struct tty_struct *tty, char ch);
+ *
+ * 	This routine is used to send a high-priority XON/XOFF

+ * ssize_t (*read)(struct tty_struct * tty, struct file * file,

+ *
+ * 	This function is called when the user requests to read from

+ *

+ *	This function is called when the user requests an ioctl which

+ * 	It is intended for ioctls which affect line discpline
+ * 	operation.  Note that the search order for ioctls is (1) tty

+ * To write a force-feedback-capable driver, the upload_effect
+ * and erase_effect callbacks in input_dev must be implemented.
+ * The uinput driver will generate a fake input event when one of
+ * these callbacks are invoked. The userspace code then uses
+ * ioctls to retrieve additional parameters and send the return code.
+ * The callback blocks until this return code is sent.
+ *
+ * The described callback mechanism is only used if ff_effects_max
+ * is set.
+ *
+ * To implement upload_effect():
+ *   1. Wait for an event with type == EV_UINPUT and code == UI_FF_UPLOAD.
+ *      A request ID will be given in 'value'.
+ *   2. Allocate a uinput_ff_upload struct, fill in request_id with
+ *      the 'value' from the EV_UINPUT event.
+ *   3. Issue a UI_BEGIN_FF_UPLOAD ioctl, giving it the
+ *      uinput_ff_upload struct. It will be filled in with the
+ *      ff_effects passed to upload_effect().
+ *   4. Perform the effect upload, and place a return code back into
+        the uinput_ff_upload struct.
+ *   5. Issue a UI_END_FF_UPLOAD ioctl, also giving it the
+ *      uinput_ff_upload_effect struct. This will complete execution
+ *      of our upload_effect() handler.
+ *
+ * To implement erase_effect():
+ *   1. Wait for an event with type == EV_UINPUT and code == UI_FF_ERASE.
+ *      A request ID will be given in 'value'.
+ *   2. Allocate a uinput_ff_erase struct, fill in request_id with
+ *      the 'value' from the EV_UINPUT event.
+ *   3. Issue a UI_BEGIN_FF_ERASE ioctl, giving it the
+ *      uinput_ff_erase struct. It will be filled in with the
+ *      effect ID passed to erase_effect().
+ *   4. Perform the effect erasure, and place a return code back

+ *      thread. See __usb_queue_reset_device().

+ * USB device drivers attach to interfaces on a physical device.  Each
+ * interface encapsulates a single high level function, such as feeding
+ * an audio stream to a speaker or reporting a change in a volume control.
+ * Many USB devices only have one interface.  The protocol used to talk to
+ * an interface's endpoints can be defined in a usb "class" specification,
+ * or by a product's vendor.  The (default) control endpoint is part of
+ * every interface, but is never listed among the interface's descriptors.
+ *
+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings.  The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface().  Alternate settings are often
+ * used to control the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings.  But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow.  Use usb_altnum_to_altsetting() to

+/**
+ * struct urb - USB Request Block
+ * @urb_list: For use by current owner of the URB.
+ * @anchor_list: membership in the list of an anchor
+ * @anchor: to anchor URBs to a common mooring
+ * @ep: Points to the endpoint's data structure.  Will eventually
+ *	replace @pipe.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ *	Create these values with the eight macros available;
+ *	usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ *	(control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ *	For example usb_sndbulkpipe() or usb_rcvintpipe().  Endpoint
+ *	numbers range from zero to fifteen.  Note that "in" endpoint two
+ *	is a different endpoint (and pipe) from "out" endpoint two.
+ *	The current configuration controls the existence, type, and
+ *	maximum packet size of any given endpoint.
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ *	status of the particular request.  ISO requests only use it
+ *	to tell whether the URB was unlinked; detailed status for
+ *	each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ *	submission, unlinking, or operation are handled.  Different
+ *	kinds of URB can use different flags.
+ * @transfer_buffer:  This identifies the buffer to (or from) which the I/O
+ *	request will be performed unless URB_NO_TRANSFER_DMA_MAP is set
+ *	(however, do not leave garbage in transfer_buffer even then).
+ *	This buffer must be suitable for DMA; allocate it with
+ *	kmalloc() or equivalent.  For transfers to "in" endpoints, contents
+ *	of this buffer will be modified.  This buffer is used for the data
+ *	stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ *	the device driver is saying that it provided this DMA address,
+ *	which the host controller driver should use in preference to the
+ *	transfer_buffer.
+ * @sg: scatter gather buffer list
+ * @num_sgs: number of entries in the sg list
+ * @transfer_buffer_length: How big is transfer_buffer.  The transfer may
+ *	be broken up into chunks according to the current maximum packet
+ *	size for the endpoint, which is a function of the configuration
+ *	and is encoded in the pipe.  When the length is zero, neither
+ *	transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ *	it tells how many bytes (out of transfer_buffer_length) were
+ *	transferred.  It will normally be the same as requested, unless
+ *	either an error was reported or a short read was performed.
+ *	The URB_SHORT_NOT_OK transfer flag may be used to make such
+ *	short reads be reported as errors.
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ *	of setup data.  Control transfers always start by sending this data
+ *	to the device.  Then transfer_buffer is read or written, if needed.
+ * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the
+ *	device driver has provided this DMA address for the setup packet.
+ *	The host controller driver should use this in preference to
+ *	setup_packet, but the HCD may chose to ignore the address if it must
+ *	copy the setup packet into internal structures.  Therefore, setup_packet
+ *	must always point to a valid buffer.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ *	transfers.  The units are frames (milliseconds) for full and low
+ *	speed devices, and microframes (1/8 millisecond) for highspeed ones.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions.  This normally points to
+ *	request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ *	completion function.  The completion function may then do what
+ *	it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
+ *	collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests.  URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions.  URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool.  That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred.  Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags,
+ * which tell the host controller driver that no such mapping is needed since
+ * the device driver is DMA-aware.  For example, a device driver might
+ * allocate a DMA buffer with usb_buffer_alloc() or call usb_buffer_map().
+ * When these transfer flags are provided, host controller drivers will
+ * attempt to use the dma addresses found in the transfer_dma and/or
+ * setup_dma fields rather than determining a dma address themselves.
+ *
+ * Note that transfer_buffer must still be set if the controller
+ * does not support DMA (as indicated by bus.uses_dma) and when talking
+ * to root hub. If you have to trasfer between highmem zone and the device
+ * on such controller, create a bounce buffer or bail out with an error.
+ * If transfer_buffer cannot be set (is in highmem) and the controller is DMA
+ * capable, assign NULL to it, so that usbmon knows not to use the value.
+ * The setup_packet must always be set, so it cannot be located in highmem.
+ *
+ * Initialization:
+ *
+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields.  All URBs must also initialize
+ * transfer_buffer and transfer_buffer_length.  They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a setup_packet.  The setup_packet and
+ * transfer_buffer may each be mapped for DMA or not, independently of
+ * the other.  The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and
+ * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped.
+ * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers.  After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals.  (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling
+ * the host controller to schedule the transfer as soon as bandwidth
+ * utilization allows, and then set start_frame to reflect the actual frame
+ * selected during submission.  Otherwise drivers must specify the start_frame
+ * and handle the case where the transfer can't begin then.  However, drivers
+ * won't know how bandwidth is currently allocated, and while they can
+ * find the current frame using usb_get_current_frame_number () they can't
+ * know the range for that frame number.  (Ranges for frame counter values
+ * are HC-specific, and can go from 256 to 65536 frames from "now".)
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort".  Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end.  Each such packet is an individual ISO transfer.  Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs.  It is used to report
+ * unlinked URBs, and status for all non-ISO transfers.  It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant
+ * driver or request state.
+ *
+ * When the completion callback is invoked for non-isochronous URBs, the
+ * actual_length field tells how many bytes were transferred.  This field
+ * is updated even when the URB terminated with an error or was unlinked.
+ *
+ * ISO transfer status is reported in the status and actual_length fields
+ * of the iso_frame_desc array, and the number of errors is reported in
+ * error_count.  Completion callbacks for ISO transfers will normally
+ * (re)submit URBs to ensure a constant transfer rate.
+ *
+ * Note that even fields marked "public" should not be touched by the driver
+ * when the urb is owned by the hcd, that is, since the call to
+ * usb_submit_urb() till the entry into the completion routine.

+ *
+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ *     probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never

+/**
+ * struct usb_function - describes one function of a configuration
+ * @name: For diagnostics, identifies the function.
+ * @strings: tables of strings, keyed by identifiers assigned during bind()
+ *	and by language IDs provided in control requests
+ * @descriptors: Table of full (or low) speed descriptors, using interface and
+ *	string identifiers assigned during @bind().  If this pointer is null,
+ *	the function will not be available at full speed (or at low speed).
+ * @hs_descriptors: Table of high speed descriptors, using interface and
+ *	string identifiers assigned during @bind().  If this pointer is null,
+ *	the function will not be available at high speed.
+ * @config: assigned when @usb_add_function() is called; this is the
+ *	configuration with which this function is associated.
+ * @bind: Before the gadget can register, all of its functions bind() to the
+ *	available resources including string and interface identifiers used
+ *	in interface or class descriptors; endpoints; I/O buffers; and so on.
+ * @unbind: Reverses @bind; called as a side effect of unregistering the
+ *	driver which added this function.
+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ *	initialize usb_ep.driver data at this time (when it is used).
+ *	Note that setting an interface to its current altsetting resets
+ *	interface state, and that all interfaces have a disabled state.
+ * @get_alt: Returns the active altsetting.  If this is not provided,
+ *	then only altsetting zero is supported.
+ * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
+ *	include host resetting or reconfiguring the gadget, and disconnection.
+ * @setup: Used for interface-specific control requests.
+ * @suspend: Notifies functions when the host stops sending USB traffic.
+ * @resume: Notifies functions when the host restarts USB traffic.
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds.  Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver.  Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation.  Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once.  If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations.  An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+ * struct usb_request - describes one i/o request
+ * @buf: Buffer used for data.  Always provide this; some controllers
+ *	only use PIO, or don't use DMA for some endpoints.
+ * @dma: DMA address corresponding to 'buf'.  If you don't set this
+ *	field, and the usb controller needs one, it is responsible
+ *	for mapping and unmapping the buffer.
+ * @length: Length of that data
+ * @no_interrupt: If true, hints that no completion irq is needed.
+ *	Helpful sometimes with deep request queues that are handled
+ *	directly by DMA controllers.
+ * @zero: If true, when writing data, makes the last packet be "short"
+ *     by adding a zero length packet as needed;
+ * @short_not_ok: When reading data, makes short packets be
+ *     treated as errors (queue stops advancing till cleanup).
+ * @complete: Function called when request completes, so this request and
+ *	its buffer may be re-used.  The function will always be called with
+ *	interrupts disabled, and it must not sleep.
+ *	Reads terminate with a short packet, or when the buffer fills,
+ *	whichever comes first.  When writes terminate, some data bytes
+ *	will usually still be in flight (often in a hardware fifo).
+ *	Errors (for reads or writes) stop the queue from advancing
+ *	until the completion function returns, so that any transfers
+ *	invalidated by the error may first be dequeued.
+ * @context: For use by the completion callback
+ * @list: For use by the gadget driver.
+ * @status: Reports completion code, zero or a negative errno.
+ *	Normally, faults block the transfer queue from advancing until
+ *	the completion callback returns.
+ *	Code "-ESHUTDOWN" indicates completion caused by device disconnect,
+ *	or when the driver disabled the endpoint.
+ * @actual: Reports bytes transferred to/from the buffer.  For reads (OUT
+ *	transfers) this may be less than the requested length.  If the
+ *	short_not_ok flag is set, short reads are treated as errors
+ *	even when status otherwise indicates successful completion.
+ *	Note that for writes (IN transfers) some data bytes may still
+ *	reside in a device-side FIFO when the request is reported as
+ *	complete.
+ *
+ * These are allocated/freed through the endpoint they're used with.  The
+ * hardware's driver can add extra per-request data to the memory it returns,
+ * which often avoids separate memory allocations (potential failures),
+ * later when the request is queued.

+ *	may not sleep.  Some devices can't detect disconnect, so this might
+ *	not be called except as part of controller shutdown.
+ * @unbind: Invoked when the driver is unbound from a gadget,
+ *	usually from rmmod (after a disconnect is reported).
+ *	Called in a context that permits sleeping.
+ * @suspend: Invoked on USB suspend.  May be called in_interrupt.
+ * @resume: Invoked on USB resume.  May be called in_interrupt.
+ * @driver: Driver model state for this driver.
+ *
+ * Devices are disabled till a gadget driver successfully bind()s, which
+ * means the driver will handle setup() requests needed to enumerate (and
+ * meet "chapter 9" requirements) then do some useful work.
+ *
+ * If gadget->is_otg is true, the gadget driver must provide an OTG
+ * descriptor during enumeration, or else fail the bind() call.  In such
+ * cases, no USB traffic may flow until both bind() returns without
+ * having called usb_gadget_disconnect(), and the USB host stack has
+ * initialized.
+ *
+ * Drivers use hardware-specific knowledge to configure the usb hardware.
+ * endpoint addressing is only one of several hardware characteristics that
+ * are in descriptors the ep0 implementation returns from setup() calls.
+ *
+ * Except for ep0 implementation, most driver code shouldn't need change to
+ * run on top of different usb controllers.  It'll use endpoints set up by
+ * that ep0 implementation.
+ *
+ * The usb controller driver handles a few standard usb requests.  Those
+ * include set_address, and feature flags for devices, interfaces, and
+ * endpoints (the get_status, set_feature, and clear_feature requests).
+ *
+ * Accordingly, the driver's setup() callback must always implement all
+ * get_descriptor requests, returning at least a device descriptor and
+ * a configuration descriptor.  Drivers must make sure the endpoint
+ * descriptors match any hardware constraints. Some hardware also constrains
+ * other descriptors. (The pxa250 allows only configurations 1, 2, or 3).
+ *
+ * The driver's setup() callback must also implement set_configuration,
+ * and should also implement set_interface, get_configuration, and
+ * get_interface.  Setting a configuration (or interface) is where
+ * endpoints should be activated or (config 0) shut down.
+ *
+ * (Note that only the default control endpoint is supported.  Neither
+ * hosts nor devices generally support control traffic except to ep0.)
+ *
+ * Most devices will ignore USB suspend/resume operations, and so will
+ * not provide those callbacks.  However, some may need to change modes
+ * when the host is not longer directing those activities.  For example,
+ * local controls (buttons, dials, etc) may need to be re-enabled since
+ * the (remote) host can't do that any longer; or an error state might
+ * be cleared, to make the device behave identically whether or not
+ * power is maintained.

+ * @probe: pointer to the driver's probe function.
+ *	This will be called when the device is inserted into the system,
+ *	but before the device has been fully initialized by the usb_serial
+ *	subsystem.  Use this function to download any firmware to the device,
+ *	or any other early initialization that might be needed.

+ * @attach: pointer to the driver's attach function.

+ * @disconnect: pointer to the driver's disconnect function.  This will be

+ * @release: pointer to the driver's release function.  This will be called
+ *	when the usb_serial data structure is about to be destroyed.
+ * @usb_driver: pointer to the struct usb_driver that controls this

+ *	the driver from sysfs.
+ *
+ * This structure is defines a USB Serial driver.  It provides all of
+ * the information that the USB serial core code needs.  If the function
+ * pointers are defined, then the USB serial core code will call them when
+ * the corresponding tty port functions are called.  If they are not
+ * called, the generic serial function will be used instead.
+ *
+ * The driver.owner field should be set to the module owner of this driver.
+ * The driver.name field should be set to the name of this driver (remember
+ * it will show up in sysfs, so it needs to be short and to the point.

+ *  The vstusb driver supports two interfaces:

+ *  	interface to any pipe with timeout support;
+ *  2 - standard read/write with ioctl config - offers standard read/write
+ *  	interface with ioctl configured pipes and timeouts.
+ *
+ *  Both interfaces can be signal from other process and will abort its i/o
+ *  operation.
+ *
+ *  A timeout of 0 means NO timeout.  The user can still terminate the read via
+ *  signal.
+ *
+ *  If using multiple threads with this driver, the user should ensure that
+ *  any reads, writes, or ioctls are complete before closing the device.

+ * register tables with the known events and their sizes, and then we

+ *
+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
+ * controller, host controller) are presented as devices on the "umc"
+ * bus.
+ *
+ * The radio controller is not strictly a UMC capability but it's
+ * useful to present it as such.
+ *
+ * References:
+ *
+ *   [WHCI] Wireless Host Controller Interface Specification for
+ *          Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.

+ *     or %WIMAX_ST_RADIO_OFF in _probe() after the call to
+ *     wimax_dev_add().
+ *     It is recommended that the driver leaves this state when
+ *     calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
+ *     down'.
+ *
+ * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
+ *     operations are allowed to proceed except the ones needed to
+ *     complete the device clean up process.
+ *
+ * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
+ *     is setup, but the device still requires some configuration
+ *     before being operational.
+ *     Some WiMAX API calls might work.
+ *
+ * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
+ *     by hardware or software switches).
+ *     It is recommended to always leave the device in this state
+ *     after initialization.
+ *
+ * @WIMAX_ST_READY: The device is fully up and radio is on.
+ *
+ * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
+ *     scan. In this state, the device cannot be actively connected to
+ *     a network.
+ *
+ * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
+ *     state exists because in some devices, the connect process can
+ *     include a number of negotiations between user space, kernel
+ *     space and the device. User space needs to know what the device
+ *     is doing. If the connect sequence in a device is atomic and
+ *     fast, the device can transition directly to CONNECTED
+ *
+ * @WIMAX_ST_CONNECTED: The device is connected to a network.
+ *
+ * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
+ *     maximum numeric value of states.
+ *
+ * Description:
+ *
+ * Transitions from one state to another one are atomic and can only
+ * be caused in kernel space with wimax_state_change(). To read the
+ * state, use wimax_state_get().
+ *
+ * States starting with __ are internal and shall not be used or
+ * referred to by drivers or userspace. They look ugly, but that's the
+ * point -- if any use is made non-internal to the stack, it is easier
+ * to catch on review.
+ *
+ * All API operations [with well defined exceptions] will take the
+ * device mutex before starting and then check the state. If the state
+ * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
+ * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
+ * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
+ *
+ * The order of the definitions is important, so we can do numerical
+ * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
+ * to operate).
+ */
+/*
+ * The allowed state transitions are described in the table below
+ * (states in rows can go to states in columns where there is an X):

+ *
+ *
+ * EXECUTING DEBUGGING ACTIONS OR NOT
+ *
+ * The main thing this framework provides is decission power to take a
+ * debug action (like printing a message) if the current debug level
+ * allows it.
+ *
+ * The decission power is at two levels: at compile-time (what does
+ * not make it is compiled out) and at run-time. The run-time
+ * selection is done per-submodule (as they are declared by the user
+ * of the framework).
+ *
+ * A call to d_test(L) (L being the target debug level) returns true
+ * if the action should be taken because the current debug levels
+ * allow it (both compile and run time).
+ *
+ * It follows that a call to d_test() that can be determined to be
+ * always false at compile time will get the code depending on it
+ * compiled out by optimization.
+ *
+ *
+ * DEBUG LEVELS
+ *
+ * It is up to the caller to define how much a debugging level is.
+ *
+ * Convention sets 0 as "no debug" (so an action marked as debug level 0
+ * will always be taken). The increasing debug levels are used for
+ * increased verbosity.
+ *
+ *
+ * USAGE
+ *
+ * Group the code in modules and submodules inside each module [which
+ * in most cases maps to Linux modules and .c files that compose
+ * those].
+ *
+ *
+ * For each module, there is:
+ *
+ *  - a MODULENAME (single word, legal C identifier)
+ *
+ *  - a debug-levels.h header file that declares the list of
+ *    submodules and that is included by all .c files that use
+ *    the debugging tools. The file name can be anything.
+ *
+ *  - some (optional) .c code to manipulate the runtime debug levels
+ *    through debugfs.
+ *
+ * The debug-levels.h file would look like:
+ *
+ *     #ifndef __debug_levels__h__
+ *     #define __debug_levels__h__
+ *
+ *     #define D_MODULENAME modulename
+ *     #define D_MASTER 10
+ *
+ *     #include <linux/wimax/debug.h>
+ *
+ *     enum d_module {
+ *             D_SUBMODULE_DECLARE(submodule_1),
+ *             D_SUBMODULE_DECLARE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DECLARE(submodule_N)
+ *     };
+ *
+ *     #endif
+ *
+ * D_MASTER is the maximum compile-time debug level; any debug actions
+ * above this will be out. D_MODULENAME is the module name (legal C
+ * identifier), which has to be unique for each module (to avoid
+ * namespace collisions during linkage). Note those #defines need to
+ * be done before #including debug.h
+ *
+ * We declare N different submodules whose debug level can be
+ * independently controlled during runtime.
+ *
+ * In a .c file of the module (and only in one of them), define the
+ * following code:
+ *
+ *     struct d_level D_LEVEL[] = {
+ *             D_SUBMODULE_DEFINE(submodule_1),
+ *             D_SUBMODULE_DEFINE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DEFINE(submodule_N),
+ *     };
+ *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
+ *
+ * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
+ * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
+ * #defined also in this file.
+ *
+ * To manipulate from user space the levels, create a debugfs dentry
+ * and then register each submodule with:
+ *
+ *     result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ *     if (result < 0)
+ *            goto error;
+ *
+ * Where PREFIX_ is a name of your chosing. This will create debugfs
+ * file with a single numeric value that can be use to tweak it. To
+ * remove the entires, just use debugfs_remove_recursive() on 'parent'.
+ *
+ * NOTE: remember that even if this will show attached to some
+ *     particular instance of a device, the settings are *global*.
+ *
+ *
+ * On each submodule (for example, .c files), the debug infrastructure
+ * should be included like this:
+ *
+ *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
+ *     #include "debug-levels.h"
+ *
+ * after #including all your include files.
+ *
+ *
+ * Now you can use the d_*() macros below [d_test(), d_fnstart(),
+ * d_fnend(), d_printf(), d_dump()].
+ *
+ * If their debug level is greater than D_MASTER, they will be
+ * compiled out.
+ *
+ * If their debug level is lower or equal than D_MASTER but greater
+ * than the current debug level of their submodule, they'll be
+ * ignored.
+ *
+ * Otherwise, the action will be performed.

+ *  - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ *   COMMAND:  implies a request from the host to the device requesting
+ *             an action being performed. The device will reply with a
+ *             message (with the same type as the command), status and
+ *             no (TLV) payload. Execution of a command might cause
+ *             events (of different type) to be sent later on as
+ *             device's state changes.
+ *
+ *   GET/SET:  similar to COMMAND, but will not cause other
+ *             EVENTs. The reply, in the case of GET, will contain
+ *             TLVs with the requested information.
+ *
+ *   EVENT:    asynchronous messages sent from the device, maybe as a
+ *             consequence of previous COMMANDs but disassociated from
+ *             them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ *  I2400M_MT_*   Message types
+ *  I2400M_MS_*   Message status (for replies, events)
+ *  i2400m_tlv_*  TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands.  This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ *	# net/core/dev.c (two place + add include)
+ *	# net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ *	# net/core/dev.c (two other places)
+ *	# include/linux/netdevice.h (one place)
+ *	# include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ *	# include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ *	# net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ *	# net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio.
+
+     The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+  
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows. inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing
+    will resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there
+    is no more input data or no more space in the output buffer (see below
+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+  if and when it gets to the next deflate block boundary. When decoding the
+  zlib or gzip format, this will cause inflate() to return immediately after
+  the header and before the first block. When doing a raw inflate, inflate()
+  will go ahead and process the first block, and will return when it gets to
+  the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64
+  if inflate() is currently decoding the last block in the deflate stream,
+  plus 128 if inflate() returned immediately after decoding an end-of-block
+  code or decoding the complete header up to just before the first byte of the
+  deflate stream. The end-of-block will not be indicated until all of the
+  uncompressed data from that block has been written to strm->next_out.  The
+  number of unused bits may in general be greater than seven, except when
+  bit 7 of data_type is set, in which case the number of unused bits will be
+  less than eight.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster approach
+  may be used for the single inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call. So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below. At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically.  Any information
+  contained in the gzip header is not retained, so applications that need that
+  information should instead use raw inflate, see inflateInit2() below, or
+  inflateBack() and perform their own processing of the gzip header and
+  trailer.

+
+     This is another version of deflateInit with more compression options. The
+   fields next_in, zalloc, zfree and opaque must be initialized before by
+   the caller.
+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.
+
+      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid
+   method). msg is set to null if there is no error message.  deflateInit2 does
+   not perform any compression: this will be done by deflate().

+
+     The dictionary should consist of strings (byte sequences) that are likely

+
+     The windowBits parameter is the base two logarithm of the maximum window

+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
+   determines the window size. inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not

+   recommended that a check value such as an adler32 or a crc32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is. Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding. Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will

+   Without this the audio standard detection will fail and you will
+   only get mono.
+
+   Since loading the firmware is often problematic when the driver is
+   compiled into the kernel I recommend postponing calling this function
+   until the first open of the video device. Another reason for
+   postponing it is that loading this firmware takes a long time (seconds)
+   due to the slow i2c bus speed. So it will speed up the boot process if
+   you can avoid loading the fw as long as the video device isn't used. */

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' arg of the s_routing function:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' arg of the s_routing function you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

+
+/* The msp has up to 5 DSP outputs, each output can independently select
+   a DSP input.
+
+   The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+   (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+   There also is a quasi-peak detector output, but that is not used by
+   this driver and is set to the same input as the loudspeaker output.
+   Not all outputs are supported by all msp models. Setting the input
+   of an unsupported output will be ignored by the driver.
+
+   There are up to 16 DSP inputs to choose from, so each output is
+   assigned 4 bits.
+
+   Note: the 44x8G can mix two inputs and feed the result back to the
+   DSP. This is currently not implemented. Also not implemented is the
+   multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
+   a need for one of those features then additional support can be added. */

+/* Sub-devices are devices that are connected somehow to the main bridge

+   sensors and webcam controllers.
+
+   Usually these devices are controlled through an i2c bus, but other busses
+   may also be used.
+
+   The v4l2_subdev struct provides a way of accessing these devices in a
+   generic manner. Most operations that these sub-devices support fall in
+   a few categories: core ops, audio ops, video ops and tuner ops.
+
+   More categories can be added if needed, although this should remain a
+   limited set (no more than approx. 8 categories).
+
+   Each category has its own set of ops that subdev drivers can implement.
+
+   A subdev driver can leave the pointer to the category ops NULL if
+   it does not implement them (e.g. an audio subdev will generally not
+   implement the video category ops). The exception is the core category:
+   this must always be present.
+
+   These ops are all used internally so it is no problem to change, remove
+   or add ops or move ops from one to another category. Currently these
+   ops are based on the original ioctls, but since ops are not limited to
+   one argument there is room for improvement here once all i2c subdev
+   drivers are converted to use these ops.
+ */
+
+/* Core ops: it is highly recommended to implement at least these ops:
+
+   g_chip_ident
+   log_status
+   g_register
+   s_register
+
+   This provides basic debugging support.
+
+   The ioctl ops is meant for generic ioctl-like commands. Depending on
+   the use-case it might be better to use subdev-specific ops (currently
+   not yet implemented) since ops provide proper type-checking.

+
+   init: initialize the sensor registors to some sort of reasonable default
+	values. Do not use for new drivers and should be removed in existing
+	drivers.
+
+   load_fw: load firmware.

+   reset: generic reset command. The argument selects which subsystems to

+	drivers without discussing this first on the linux-media mailinglist.
+	There should be no reason normally to reset a device.

+/*
+ * UBI device creation (the same as MTD device attachment)
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * MTD devices may be attached using %UBI_IOCATT ioctl command of the UBI
+ * control device. The caller has to properly fill and pass
+ * &struct ubi_attach_req object - UBI will attach the MTD device specified in
+ * the request and return the newly created UBI device number as the ioctl
+ * return value.
+ *
+ * UBI device deletion (the same as MTD device detachment)
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * An UBI device maybe deleted with %UBI_IOCDET ioctl command of the UBI
+ * control device.
+ *
+ * UBI volume creation
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * UBI volumes are created via the %UBI_IOCMKVOL ioctl command of UBI character
+ * device. A &struct ubi_mkvol_req object has to be properly filled and a
+ * pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume deletion
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To delete a volume, the %UBI_IOCRMVOL ioctl command of the UBI character
+ * device should be used. A pointer to the 32-bit volume ID hast to be passed
+ * to the ioctl.
+ *
+ * UBI volume re-size
+ * ~~~~~~~~~~~~~~~~~~
+ *
+ * To re-size a volume, the %UBI_IOCRSVOL ioctl command of the UBI character
+ * device should be used. A &struct ubi_rsvol_req object has to be properly
+ * filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volumes re-name
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To re-name several volumes atomically at one go, the %UBI_IOCRNVOL command
+ * of the UBI character device should be used. A &struct ubi_rnvol_req object
+ * has to be properly filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume update
+ * ~~~~~~~~~~~~~~~~~
+ *
+ * Volume update should be done via the %UBI_IOCVOLUP ioctl command of the
+ * corresponding UBI volume character device. A pointer to a 64-bit update
+ * size should be passed to the ioctl. After this, UBI expects user to write
+ * this number of bytes to the volume character device. The update is finished
+ * when the claimed number of bytes is passed. So, the volume update sequence
+ * is something like:
+ *
+ * fd = open("/dev/my_volume");
+ * ioctl(fd, UBI_IOCVOLUP, &image_size);
+ * write(fd, buf, image_size);
+ * close(fd);
+ *
+ * Logical eraseblock erase
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To erase a logical eraseblock, the %UBI_IOCEBER ioctl command of the
+ * corresponding UBI volume character device should be used. This command
+ * unmaps the requested logical eraseblock, makes sure the corresponding
+ * physical eraseblock is successfully erased, and returns.
+ *
+ * Atomic logical eraseblock change
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Atomic logical eraseblock change operation is called using the %UBI_IOCEBCH
+ * ioctl command of the corresponding UBI volume character device. A pointer to
+ * a &struct ubi_leb_change_req object has to be passed to the ioctl. Then the
+ * user is expected to write the requested amount of bytes (similarly to what
+ * should be done in case of the "volume update" ioctl).
+ *
+ * Logical eraseblock map
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To map a logical eraseblock to a physical eraseblock, the %UBI_IOCEBMAP
+ * ioctl command should be used. A pointer to a &struct ubi_map_req object is
+ * expected to be passed. The ioctl maps the requested logical eraseblock to
+ * a physical eraseblock and returns.  Only non-mapped logical eraseblocks can
+ * be mapped. If the logical eraseblock specified in the request is already
+ * mapped to a physical eraseblock, the ioctl fails and returns error.
+ *
+ * Logical eraseblock unmap
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To unmap a logical eraseblock to a physical eraseblock, the %UBI_IOCEBUNMAP
+ * ioctl command should be used. The ioctl unmaps the logical eraseblocks,
+ * schedules corresponding physical eraseblock for erasure, and returns. Unlike
+ * the "LEB erase" command, it does not wait for the physical eraseblock being
+ * erased. Note, the side effect of this is that if an unclean reboot happens
+ * after the unmap ioctl returns, you may find the LEB mapped again to the same
+ * physical eraseblock after the UBI is run again.
+ *
+ * Check if logical eraseblock is mapped
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To check if a logical eraseblock is mapped to a physical eraseblock, the
+ * %UBI_IOCEBISMAP ioctl command should be used. It returns %0 if the LEB is
+ * not mapped, and %1 if it is mapped.
+ *
+ * Set an UBI volume property
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To set an UBI volume property the %UBI_IOCSETPROP ioctl command should be
+ * used. A pointer to a &struct ubi_set_prop_req object is expected to be
+ * passed. The object describes which property should be set, and to which value
+ * it should be set.

+ *
+ * This data structure is used to specify MTD device UBI has to attach and the

+ * device is passed in @ubi_num. UBI may automatically assign the number if
+ * @UBI_DEV_NUM_AUTO is passed. In this case, the device number is returned in
+ * @ubi_num.
+ *
+ * Most applications should pass %0 in @vid_hdr_offset to make UBI use default
+ * offset of the VID header within physical eraseblocks. The default offset is
+ * the next min. I/O unit after the EC header. For example, it will be offset
+ * 512 in case of a 512 bytes page NAND flash with no sub-page support. Or
+ * it will be 512 in case of a 2KiB page NAND flash with 4 512-byte sub-pages.

+ * But in rare cases, if this optimizes things, the VID header may be placed to
+ * a different offset. For example, the boot-loader might do things faster if
+ * the VID header sits at the end of the first 2KiB NAND page with 4 sub-pages.
+ * As the boot-loader would not normally need to read EC headers (unless it
+ * needs UBI in RW mode), it might be faster to calculate ECC. This is weird
+ * example, but it real-life example. So, in this example, @vid_hdr_offer would
+ * be 2KiB-64 bytes = 1984. Note, that this position is not even 512-bytes

+ * The dn_dev_parms structure contains the set of parameters
+ * for each device (hence inclusion in the dn_dev structure)
+ * and an array is used to store the default types of supported
+ * device (in dn_dev.c).
+ *
+ * The type field matches the ARPHRD_ constants and is used in
+ * searching the list for supported devices when new devices
+ * come up.
+ *
+ * The mode field is used to find out if a device is broadcast,
+ * multipoint, or pointopoint. Please note that DECnet thinks
+ * different ways about devices to the rest of the kernel
+ * so the normal IFF_xxx flags are invalid here. For devices
+ * which can be any combination of the previously mentioned
+ * attributes, you can set this on a per device basis by
+ * installing an up() routine.
+ *
+ * The device state field, defines the initial state in which the
+ * device will come up. In the dn_dev structure, it is the actual
+ * state.
+ *
+ * Things have changed here. I've killed timer1 since it's a user space
+ * issue for a user space routing deamon to sort out. The kernel does
+ * not need to be bothered with it.
+ *
+ * Timers:
+ * t2 - Rate limit timer, min time between routing and hello messages
+ * t3 - Hello timer, send hello messages when it expires
+ *
+ * Callbacks:
+ * up() - Called to initialize device, return value can veto use of
+ *        device with DECnet.
+ * down() - Called to turn device off when it goes down
+ * timer3() - Called once for each ifaddr when timer 3 goes off
+ * 
+ * sysctl - Hook for sysctl things

+ * an application.  In essence:
+ *
+ *	1) Sockets bound to different interfaces may share a local port.
+ *	   Failing that, goto test 2.
+ *	2) If all sockets have sk->sk_reuse set, and none of them are in
+ *	   TCP_LISTEN state, the port may be shared.
+ *	   Failing that, goto test 3.
+ *	3) If all sockets are bound to a specific inet_sk(sk)->rcv_saddr local
+ *	   address, and none of them are the same, the port may be
+ *	   shared.
+ *	   Failing this, the port cannot be shared.
+ *
+ * The interesting point, is test #2.  This is what an FTP server does
+ * all day.  To optimize this case we use a specific flag bit defined
+ * below.  As we add sockets to a bind bucket list, we perform a
+ * check of: (newsk->sk_reuse && (newsk->sk_state != TCP_LISTEN))
+ * As long as all sockets added to a bind bucket pass this test,
+ * the flag bit will be set.
+ * The resulting situation is that tcp_v[46]_verify_bind() can just check
+ * for this flag bit, if it is set and the socket trying to bind has
+ * sk->sk_reuse set, we don't even have to walk the owners list at all,
+ * we return that it is ok to bind this socket to the requested local port.
+ *
+ * Sounds like a lot of work, but it is worth it.  In a more naive
+ * implementation (ie. current FreeBSD etc.) the entire list of ports
+ * must be walked for each data port opened by an ftp server.  Needless
+ * to say, this does not scale at all.  With a couple thousand FTP
+ * users logged onto your box, isn't it nice to know that new data
+ * ports are created in O(1) time?  I thought so. ;-)	-DaveM

+
+/************************** DOCUMENTATION **************************/
+/*
+ * Initial driver API (1996 -> onward) :
+ * -----------------------------------
+ * The initial API just sends the IOCTL request received from user space
+ * to the driver (via the driver ioctl handler). The driver has to
+ * handle all the rest...
+ *
+ * The initial API also defines a specific handler in struct net_device
+ * to handle wireless statistics.
+ *
+ * The initial APIs served us well and has proven a reasonably good design.
+ * However, there is a few shortcommings :
+ *	o No events, everything is a request to the driver.
+ *	o Large ioctl function in driver with gigantic switch statement
+ *	  (i.e. spaghetti code).
+ *	o Driver has to mess up with copy_to/from_user, and in many cases
+ *	  does it unproperly. Common mistakes are :
+ *		* buffer overflows (no checks or off by one checks)
+ *		* call copy_to/from_user with irq disabled
+ *	o The user space interface is tied to ioctl because of the use
+ *	  copy_to/from_user.
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * The new driver API is just a bunch of standard functions (handlers),
+ * each handling a specific Wireless Extension. The driver just export
+ * the list of handler it supports, and those will be called apropriately.
+ *
+ * I tried to keep the main advantage of the previous API (simplicity,
+ * efficiency and light weight), and also I provide a good dose of backward
+ * compatibility (most structures are the same, driver can use both API
+ * simultaneously, ...).
+ * Hopefully, I've also addressed the shortcomming of the initial API.
+ *
+ * The advantage of the new API are :
+ *	o Handling of Extensions in driver broken in small contained functions
+ *	o Tighter checks of ioctl before calling the driver
+ *	o Flexible commit strategy (at least, the start of it)
+ *	o Backward compatibility (can be mixed with old API)
+ *	o Driver doesn't have to worry about memory and user-space issues
+ * The last point is important for the following reasons :
+ *	o You are now able to call the new driver API from any API you
+ *		want (including from within other parts of the kernel).
+ *	o Common mistakes are avoided (buffer overflow, user space copy
+ *		with irq disabled and so on).
+ *
+ * The Drawback of the new API are :
+ *	o bloat (especially kernel)
+ *	o need to migrate existing drivers to new API
+ * My initial testing shows that the new API adds around 3kB to the kernel
+ * and save between 0 and 5kB from a typical driver.
+ * Also, as all structures and data types are unchanged, the migration is
+ * quite straightforward (but tedious).
+ *
+ * ---
+ *
+ * The new driver API is defined below in this file. User space should
+ * not be aware of what's happening down there...
+ *
+ * A new kernel wrapper is in charge of validating the IOCTLs and calling
+ * the appropriate driver handler. This is implemented in :
+ *	# net/core/wireless.c
+ *
+ * The driver export the list of handlers in :
+ *	# include/linux/netdevice.h (one place)
+ *
+ * The new driver API is available for WIRELESS_EXT >= 13.
+ * Good luck with migration to the new API ;-)
+ */
+
+/* ---------------------- THE IMPLEMENTATION ---------------------- */
+/*
+ * Some of the choice I've made are pretty controversials. Defining an
+ * API is very much weighting compromises. This goes into some of the
+ * details and the thinking behind the implementation.
+ *
+ * Implementation goals :
+ * --------------------
+ * The implementation goals were as follow :
+ *	o Obvious : you should not need a PhD to understand what's happening,
+ *		the benefit is easier maintainance.
+ *	o Flexible : it should accommodate a wide variety of driver
+ *		implementations and be as flexible as the old API.
+ *	o Lean : it should be efficient memory wise to minimise the impact
+ *		on kernel footprint.
+ *	o Transparent to user space : the large number of user space
+ *		applications that use Wireless Extensions should not need
+ *		any modifications.
+ *
+ * Array of functions versus Struct of functions
+ * ---------------------------------------------
+ * 1) Having an array of functions allow the kernel code to access the
+ * handler in a single lookup, which is much more efficient (think hash
+ * table here).
+ * 2) The only drawback is that driver writer may put their handler in
+ * the wrong slot. This is trivial to test (I set the frequency, the
+ * bitrate changes). Once the handler is in the proper slot, it will be
+ * there forever, because the array is only extended at the end.
+ * 3) Backward/forward compatibility : adding new handler just require
+ * extending the array, so you can put newer driver in older kernel
+ * without having to patch the kernel code (and vice versa).
+ *
+ * All handler are of the same generic type
+ * ----------------------------------------
+ * That's a feature !!!
+ * 1) Having a generic handler allow to have generic code, which is more
+ * efficient. If each of the handler was individually typed I would need
+ * to add a big switch in the kernel (== more bloat). This solution is
+ * more scalable, adding new Wireless Extensions doesn't add new code.
+ * 2) You can use the same handler in different slots of the array. For
+ * hardware, it may be more efficient or logical to handle multiple
+ * Wireless Extensions with a single function, and the API allow you to
+ * do that. (An example would be a single record on the card to control
+ * both bitrate and frequency, the handler would read the old record,
+ * modify it according to info->cmd and rewrite it).
+ *
+ * Functions prototype uses union iwreq_data
+ * -----------------------------------------
+ * Some would have prefered functions defined this way :
+ *	static int mydriver_ioctl_setrate(struct net_device *dev, 
+ *					  long rate, int auto)
+ * 1) The kernel code doesn't "validate" the content of iwreq_data, and
+ * can't do it (different hardware may have different notion of what a
+ * valid frequency is), so we don't pretend that we do it.
+ * 2) The above form is not extendable. If I want to add a flag (for
+ * example to distinguish setting max rate and basic rate), I would
+ * break the prototype. Using iwreq_data is more flexible.
+ * 3) Also, the above form is not generic (see above).
+ * 4) I don't expect driver developper using the wrong field of the
+ * union (Doh !), so static typechecking doesn't add much value.
+ * 5) Lastly, you can skip the union by doing :
+ *	static int mydriver_ioctl_setrate(struct net_device *dev,
+ *					  struct iw_request_info *info,
+ *					  struct iw_param *rrq,
+ *					  char *extra)
+ * And then adding the handler in the array like this :
+ *        (iw_handler) mydriver_ioctl_setrate,             // SIOCSIWRATE
+ *
+ * Using functions and not a registry
+ * ----------------------------------
+ * Another implementation option would have been for every instance to
+ * define a registry (a struct containing all the Wireless Extensions)
+ * and only have a function to commit the registry to the hardware.
+ * 1) This approach can be emulated by the current code, but not
+ * vice versa.
+ * 2) Some drivers don't keep any configuration in the driver, for them
+ * adding such a registry would be a significant bloat.
+ * 3) The code to translate from Wireless Extension to native format is
+ * needed anyway, so it would not reduce significantely the amount of code.
+ * 4) The current approach only selectively translate Wireless Extensions
+ * to native format and only selectively set, whereas the registry approach
+ * would require to translate all WE and set all parameters for any single
+ * change.
+ * 5) For many Wireless Extensions, the GET operation return the current
+ * dynamic value, not the value that was set.
+ *
+ * This header is <net/iw_handler.h>
+ * ---------------------------------
+ * 1) This header is kernel space only and should not be exported to
+ * user space. Headers in "include/linux/" are exported, headers in
+ * "include/net/" are not.
+ *
+ * Mixed 32/64 bit issues
+ * ----------------------
+ * The Wireless Extensions are designed to be 64 bit clean, by using only
+ * datatypes with explicit storage size.
+ * There are some issues related to kernel and user space using different
+ * memory model, and in particular 64bit kernel with 32bit user space.
+ * The problem is related to struct iw_point, that contains a pointer
+ * that *may* need to be translated.
+ * This is quite messy. The new API doesn't solve this problem (it can't),
+ * but is a step in the right direction :
+ * 1) Meta data about each ioctl is easily available, so we know what type
+ * of translation is needed.
+ * 2) The move of data between kernel and user space is only done in a single
+ * place in the kernel, so adding specific hooks in there is possible.
+ * 3) In the long term, it allows to move away from using ioctl as the
+ * user space API.
+ *
+ * So many comments and so few code
+ * --------------------------------
+ * That's a feature. Comments won't bloat the resulting kernel binary.

+ * other functions in hardware interrupt context. If there is a need for such
+ * call, the low-level driver should first ACK the interrupt and perform the
+ * IEEE 802.11 code call after this, e.g. from a scheduled workqueue or even
+ * tasklet function.

+ * sent over the air except for the FCS which should be calculated by the
+ * hardware.
+ *
+ * There are, however, various exceptions to this rule for advanced features:
+ *
+ * The first exception is for hardware encryption and decryption offload
+ * where the IV/ICV may or may not be generated in hardware.
+ *
+ * Secondly, when the hardware handles fragmentation, the frame handed to
+ * the driver from mac80211 is the MSDU, not the MPDU.
+ *
+ * Finally, for received frames, the driver is able to indicate that it has
+ * filled a radiotap header and put that in front of the frame; if it does
+ * not do so then mac80211 may add this under certain circumstances.

+ *	avoid race conditions, the filter must be set by the hardware or
+ *	firmware upon receiving a frame that indicates that the station

+ * @IEEE80211_TX_INTFL_NEED_TXPROCESSING: completely internal to mac80211,

+ * @IEEE80211_TX_CTL_PSPOLL_RESPONSE: (internal?)

+ * DOC: Hardware crypto acceleration

+ * device is called to enable hardware acceleration of encryption and
+ * decryption. The callback takes a @sta parameter that will be NULL
+ * for default keys or keys used for transmission only, or point to
+ * the station information for the peer for individual keys.
+ * Multiple transmission keys with the same key index may be used when
+ * VLANs are configured for an access point.
+ *
+ * When transmitting, the TX control data will use the @hw_key_idx
+ * selected by the driver by modifying the &struct ieee80211_key_conf
+ * pointed to by the @key parameter to the set_key() function.
+ *
+ * The set_key() call for the %SET_KEY command should return 0 if
+ * the key is now in use, -%EOPNOTSUPP or -%ENOSPC if it couldn't be
+ * added; if you return 0 then hw_key_idx must be assigned to the
+ * hardware key index, you are free to use the full u8 range.
+ *
+ * When the cmd is %DISABLE_KEY then it must succeed.
+ *
+ * Note that it is permissible to not decrypt a frame even if a key
+ * for it has been uploaded to hardware, the stack will not make any
+ * decision based on whether a key has been uploaded or not but rather
+ * based on the receive flags.
+ *

+
+/**
+ * DOC: Powersave support
+ *
+ * mac80211 has support for various powersave implementations.
+ *
+ * First, it can support hardware that handles all powersaving by
+ * itself, such hardware should simply set the %IEEE80211_HW_SUPPORTS_PS
+ * hardware flag. In that case, it will be told about the desired
+ * powersave mode depending on the association status, and the driver
+ * must take care of sending nullfunc frames when necessary, i.e. when
+ * entering and leaving powersave mode. The driver is required to look at
+ * the AID in beacons and signal to the AP that it woke up when it finds
+ * traffic directed to it. This mode supports dynamic PS by simply
+ * enabling/disabling PS.
+ *
+ * Additionally, such hardware may set the %IEEE80211_HW_SUPPORTS_DYNAMIC_PS
+ * flag to indicate that it can support dynamic PS mode itself (see below).
+ *
+ * Other hardware designs cannot send nullfunc frames by themselves and also
+ * need software support for parsing the TIM bitmap. This is also supported
+ * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and
+ * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still
+ * required to pass up beacons. The hardware is still required to handle
+ * waking up for multicast traffic; if it cannot the driver must handle that
+ * as best as it can, mac80211 is too slow.
+ *
+ * Dynamic powersave mode is an extension to normal powersave mode in which
+ * the hardware stays awake for a user-specified period of time after sending
+ * a frame so that reply frames need not be buffered and therefore delayed
+ * to the next wakeup. This can either be supported by hardware, in which case
+ * the driver needs to look at the @dynamic_ps_timeout hardware configuration
+ * value, or by the stack if all nullfunc handling is in the stack.
+ */
+
+/**
+ * DOC: Beacon filter support
+ *
+ * Some hardware have beacon filter support to reduce host cpu wakeups
+ * which will reduce system power consumption. It usuallly works so that
+ * the firmware creates a checksum of the beacon but omits all constantly
+ * changing elements (TSF, TIM etc). Whenever the checksum changes the
+ * beacon is forwarded to the host, otherwise it will be just dropped. That
+ * way the host will only receive beacons where some relevant information
+ * (for example ERP protection or WMM settings) have changed.
+ *
+ * Beacon filter support is advertised with the %IEEE80211_HW_BEACON_FILTER
+ * hardware capability. The driver needs to enable beacon filter support
+ * whenever power save is enabled, that is %IEEE80211_CONF_PS is set. When
+ * power save is enabled, the stack will not check for beacon loss and the
+ * driver needs to notify about loss of beacons with ieee80211_beacon_loss().
+ *
+ * The time (or number of beacons missed) until the firmware notifies the
+ * driver of a beacon loss event (which in turn causes the driver to call
+ * ieee80211_beacon_loss()) should be configurable and will be controlled
+ * by mac80211 and the roaming algorithm in the future.
+ *
+ * Since there may be constantly changing information elements that nothing
+ * in the software stack cares about, we will, in the future, have mac80211
+ * tell the driver which information elements are interesting in the sense
+ * that we want to see changes in them. This will include
+ *  - a list of information element IDs
+ *  - a list of OUIs for the vendor information element
+ *
+ * Ideally, the hardware would filter out any beacons without changes in the
+ * requested elements, but if it cannot support that it may, at the expense
+ * of some efficiency, filter out only a subset. For example, if the device
+ * doesn't support checking for OUIs it should pass up all changes in all
+ * vendor information elements.
+ *
+ * Note that change, for the sake of simplification, also includes information
+ * elements appearing or disappearing from the beacon.
+ *
+ * Some hardware supports an "ignore list" instead, just make sure nothing
+ * that was requested is on the ignore list, and include commonly changing
+ * information element IDs in the ignore list, for example 11 (BSS load) and
+ * the various vendor-assigned IEs with unknown contents (128, 129, 133-136,
+ * 149, 150, 155, 156, 173, 176, 178, 179, 219); for forward compatibility
+ * it could also include some currently unused IDs.
+ *
+ *
+ * In addition to these capabilities, hardware should support notifying the
+ * host of changes in the beacon RSSI. This is relevant to implement roaming
+ * when no traffic is flowing (when traffic is flowing we see the RSSI of
+ * the received data packets). This can consist in notifying the host when
+ * the RSSI changes significantly or when it drops below or rises above
+ * configurable thresholds. In the future these thresholds will also be
+ * configured by mac80211 (which gets them from userspace) to implement
+ * them as the roaming algorithm requires.
+ *
+ * If the hardware cannot implement this, the driver should ask it to
+ * periodically pass beacon frames to the host so that software can do the
+ * signal strength threshold checking.
+ */
+
+/**
+ * DOC: Frame filtering
+ *
+ * mac80211 requires to see many management frames for proper
+ * operation, and users may want to see many more frames when
+ * in monitor mode. However, for best CPU usage and power consumption,
+ * having as few frames as possible percolate through the stack is
+ * desirable. Hence, the hardware should filter as much as possible.
+ *
+ * To achieve this, mac80211 uses filter flags (see below) to tell
+ * the driver's configure_filter() function which frames should be
+ * passed to mac80211 and which should be filtered out.
+ *
+ * Before configure_filter() is invoked, the prepare_multicast()
+ * callback is invoked with the parameters @mc_count and @mc_list
+ * for the combined multicast address list of all virtual interfaces.
+ * It's use is optional, and it returns a u64 that is passed to
+ * configure_filter(). Additionally, configure_filter() has the
+ * arguments @changed_flags telling which flags were changed and
+ * @total_flags with the new flag states.
+ *
+ * If your device has no multicast address filters your driver will
+ * need to check both the %FIF_ALLMULTI flag and the @mc_count
+ * parameter to see whether multicast frames should be accepted
+ * or dropped.
+ *
+ * All unsupported flags in @total_flags must be cleared.
+ * Hardware does not support a flag if it is incapable of _passing_
+ * the frame to the stack. Otherwise the driver must ignore
+ * the flag, but not clear it.
+ * You must _only_ clear the flag (announce no support for the
+ * flag to mac80211) if you are not able to pass the packet type
+ * to the stack (so the hardware always filters it).
+ * So for example, you should clear @FIF_CONTROL, if your hardware
+ * always filters control frames. If your hardware always passes
+ * control frames to the kernel and is incapable of filtering them,
+ * you do _not_ clear the @FIF_CONTROL flag.

+ *	This function should return NETDEV_TX_OK except in very

+ *	Must be implemented and atomic.
+ *
+ * @start: Called before the first netdevice attached to the hardware
+ *	is enabled. This should turn on the hardware and must turn on
+ *	frame reception (for possibly enabled monitor interfaces.)
+ *	Returns negative error codes, these may be seen in userspace,
+ *	or zero.
+ *	When the device is started it should not have a MAC address
+ *	to avoid acknowledging frames before a non-monitor device
+ *	is added.
+ *	Must be implemented.
+ *
+ * @stop: Called after last netdevice attached to the hardware
+ *	is disabled. This should turn off the hardware (at least
+ *	it must turn off frame reception.)
+ *	May be called right after add_interface if that rejects
+ *	an interface. If you added any work onto the mac80211 workqueue
+ *	you should ensure to cancel it on this callback.
+ *	Must be implemented.
+ *
+ * @add_interface: Called when a netdevice attached to the hardware is
+ *	enabled. Because it is not called for monitor mode devices, @start
+ *	and @stop must be implemented.
+ *	The driver should perform any initialization it needs before
+ *	the device can be enabled. The initial configuration for the
+ *	interface is given in the conf parameter.
+ *	The callback may refuse to add an interface by returning a
+ *	negative error code (which will be seen in userspace.)
+ *	Must be implemented.
+ *
+ * @remove_interface: Notifies a driver that an interface is going down.
+ *	The @stop callback is called after this if it is the last interface
+ *	and no monitor interfaces are present.
+ *	When all interfaces are removed, the MAC address in the hardware
+ *	must be cleared so the device no longer acknowledges packets,
+ *	the mac_addr member of the conf structure is, however, set to the
+ *	MAC address of the device going away.
+ *	Hence, this callback must be implemented.

+ * @config: Handler for configuration requests. IEEE 802.11 code calls this
+ *	function to change hardware configuration, e.g., channel.
+ *	This function should never fail but returns a negative error code
+ *	if it does.
+ *
+ * @bss_info_changed: Handler for configuration requests related to BSS
+ *	parameters that may vary during BSS's lifespan, and may affect low
+ *	level driver (e.g. assoc/disassoc status, erp parameters).
+ *	This function should not be used if no BSS has been set, unless
+ *	for association indication. The @changed parameter indicates which
+ *	of the bss parameters has changed when a call is made.
+ *
+ * @prepare_multicast: Prepare for multicast filter configuration.
+ *	This callback is optional, and its return value is passed
+ *	to configure_filter(). This callback must be atomic.
+ *
+ * @configure_filter: Configure the device's RX filter.
+ *	See the section "Frame filtering" for more information.
+ *	This callback must be implemented.
+ *
+ * @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit
+ * 	must be set or cleared for a given STA. Must be atomic.
+ *
+ * @set_key: See the section "Hardware crypto acceleration"
+ *	This callback can sleep, and is only called between add_interface
+ *	and remove_interface calls, i.e. while the given virtual interface
+ *	is enabled.
+ *	Returns a negative error code if the key can't be added.
+ *
+ * @update_tkip_key: See the section "Hardware crypto acceleration"
+ * 	This callback will be called in the context of Rx. Called for drivers
+ * 	which set IEEE80211_KEY_FLAG_TKIP_REQ_RX_P1_KEY.
+ *
+ * @hw_scan: Ask the hardware to service the scan request, no need to start
+ *	the scan state machine in stack. The scan must honour the channel
+ *	configuration done by the regulatory agent in the wiphy's
+ *	registered bands. The hardware (or the driver) needs to make sure
+ *	that power save is disabled.
+ *	The @req ie/ie_len members are rewritten by mac80211 to contain the
+ *	entire IEs after the SSID, so that drivers need not look at these
+ *	at all but just send them after the SSID -- mac80211 includes the
+ *	(extended) supported rates and HT information (where applicable).
+ *	When the scan finishes, ieee80211_scan_completed() must be called;
+ *	note that it also must be called when the scan cannot finish due to
+ *	any error unless this callback returned a negative error code.
+ *
+ * @sw_scan_start: Notifier function that is called just before a software scan
+ *	is started. Can be NULL, if the driver doesn't need this notification.
+ *
+ * @sw_scan_complete: Notifier function that is called just after a software scan
+ *	finished. Can be NULL, if the driver doesn't need this notification.
+ *
+ * @get_stats: Return low-level statistics.
+ * 	Returns zero if statistics are available.
+ *
+ * @get_tkip_seq: If your device implements TKIP encryption in hardware this
+ *	callback should be provided to read the TKIP transmit IVs (both IV32
+ *	and IV16) for the given key from hardware.
+ *
+ * @set_rts_threshold: Configuration of RTS threshold (if device needs it)
+ *
+ * @sta_notify: Notifies low level driver about addition, removal or power
+ *	state transition of an associated station, AP,  IBSS/WDS/mesh peer etc.
+ *	Must be atomic.
+ *
+ * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
+ *	bursting) for a hardware TX queue.
+ *	Returns a negative error code on failure.
+ *
+ * @get_tx_stats: Get statistics of the current TX queue status. This is used
+ *	to get number of currently queued packets (queue length), maximum queue
+ *	size (limit), and total number of packets sent using each TX queue
+ *	(count). The 'stats' pointer points to an array that has hw->queues
+ *	items.
+ *
+ * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently,
+ *	this is only used for IBSS mode BSSID merging and debugging. Is not a
+ *	required function.
+ *
+ * @set_tsf: Set the TSF timer to the specified value in the firmware/hardware.
+ *      Currently, this is only used for IBSS mode debugging. Is not a
+ *	required function.
+ *
+ * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize
+ *	with other STAs in the IBSS. This is only used in IBSS mode. This
+ *	function is optional if the firmware/hardware takes full care of
+ *	TSF synchronization.
+ *
+ * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us.
+ *	This is needed only for IBSS mode and the result of this function is
+ *	used to determine whether to reply to Probe Requests.
+ *	Returns non-zero if this device sent the last beacon.
+ *
+ * @ampdu_action: Perform a certain A-MPDU action
+ * 	The RA/TID combination determines the destination and TID we want
+ * 	the ampdu action to be performed for. The action is defined through
+ * 	ieee80211_ampdu_mlme_action. Starting sequence number (@ssn)
+ * 	is the first frame we expect to perform the action on. Notice
+ * 	that TX/RX_STOP can pass NULL for this parameter.
+ *	Returns a negative error code on failure.
+ *
+ * @rfkill_poll: Poll rfkill hardware state. If you need this, you also
+ *	need to set wiphy->rfkill_poll to %true before registration,
+ *	and need to call wiphy_rfkill_set_hw_state() in the callback.
+ *
+ * @testmode_cmd: Implement a cfg80211 test mode command.

+ * NetLabel - A management interface for maintaining network packet label

+ *
+ * Network protocols such as CIPSO and RIPSO require a label translation layer
+ * to convert the label on the packet into something meaningful on the host
+ * machine.  In the current Linux implementation these mapping tables live
+ * inside the kernel; NetLabel provides a mechanism for user space applications
+ * to manage these mapping tables.
+ *
+ * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
+ * send messages between kernel and user space.  The general format of a
+ * NetLabel message is shown below:
+ *
+ *  +-----------------+-------------------+--------- --- -- -
+ *  | struct nlmsghdr | struct genlmsghdr | payload
+ *  +-----------------+-------------------+--------- --- -- -
+ *
+ * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
+ * The payload is dependent on the subsystem specified in the
+ * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
+ * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
+ * file.  All of the fields in the NetLabel payload are NETLINK attributes, see
+ * the include/net/netlink.h file for more information on NETLINK attributes.

+ *
+ *   The meaning of these functions is equal to their lower case

+ *    call net_assign_generic() to put the private data on the struct
+ *    net (most preferably this should be done in the ->init callback
+ *    of the ops registered);
+ * 3. do not change this pointer while the net is alive;
+ * 4. do not try to have any private reference on the net_generic object.
+ *
+ * After accomplishing all of the above, the private pointer can be

+/*	Random Early Detection (RED) algorithm.
+	=======================================
+
+	Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+	for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+	This file codes a "divisionless" version of RED algorithm
+	as written down in Fig.17 of the paper.
+
+	Short description.
+	------------------
+
+	When a new packet arrives we calculate the average queue length:
+
+	avg = (1-W)*avg + W*current_queue_len,
+
+	W is the filter time constant (chosen as 2^(-Wlog)), it controls
+	the inertia of the algorithm. To allow larger bursts, W should be
+	decreased.
+
+	if (avg > th_max) -> packet marked (dropped).
+	if (avg < th_min) -> packet passes.
+	if (th_min < avg < th_max) we calculate probability:
+
+	Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+	and mark (drop) packet with this probability.
+	Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+	max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+	max_P is chosen as a number, so that max_P/(th_max-th_min)
+	is a negative power of two in order arithmetics to contain
+	only shifts.
+
+
+	Parameters, settable by user:
+	-----------------------------
+
+	qth_min		- bytes (should be < qth_max/2)
+	qth_max		- bytes (should be at least 2*qth_min and less limit)
+	Wlog	       	- bits (<32) log(1/W).
+	Plog	       	- bits (<32)
+
+	Plog is related to max_P by formula:
+
+	max_P = (qth_max-qth_min)/2^Plog;
+
+	F.e. if qth_max=128K and qth_min=32K, then Plog=22
+	corresponds to max_P=0.02
+
+	Scell_log
+	Stab
+
+	Lookup table for log((1-W)^(t/t_ave).
+
+
+	NOTES:
+
+	Upper bound on W.
+	-----------------
+
+	If you want to allow bursts of L packets of size S,
+	you should choose W:
+
+	L + 1 - th_min/S < (1-(1-W)^L)/W
+
+	th_min/S = 32         th_min/S = 4
+
+	log(W)	L
+	-1	33
+	-2	35
+	-3	39
+	-4	46
+	-5	57
+	-6	75
+	-7	101
+	-8	135
+	-9	190
+	etc.

+ * numbers have changed (bottom 5 bits).  The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowledgment, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or
+ * ack is more than 65535, an uncompressed packet is sent.)

+ * The top nibble of the first octet is the packet type.  There are
+ * three possible types: IP (not proto TCP or tcp with one of the
+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the

+ * will be a good abstraction layer. Expect this to change as more
+ * devices show in the market. This API is designed to be growable in
+ * order to address this problem.
+ *
+ * USAGE
+ *
+ * Embed a `struct wimax_dev` at the beginning of the the device's
+ * private structure, initialize and register it. For details, see
+ * `struct wimax_dev`s documentation.
+ *
+ * Once this is done, wimax-tools's libwimaxll can be used to
+ * communicate with the driver from user space. You user space
+ * application does not have to forcibily use libwimaxll and can talk
+ * the generic netlink protocol directly if desired.
+ *
+ * Remember this is a very low level API that will to provide all of
+ * WiMAX features. Other daemons and services running in user space
+ * are the expected clients of it. They offer a higher level API that
+ * applications should use (an example of this is the Intel's WiMAX
+ * Network Service for the i2400m).
+ *
+ * DESIGN
+ *
+ * Although not set on final stone, this very basic interface is
+ * mostly completed. Remember this is meant to grow as new common
+ * operations are decided upon. New operations will be added to the
+ * interface, intent being on keeping backwards compatibility as much
+ * as possible.
+ *
+ * This layer implements a set of calls to control a WiMAX device,
+ * exposing a frontend to the rest of the kernel and user space (via
+ * generic netlink) and a backend implementation in the driver through
+ * function pointers.
+ *
+ * WiMAX devices have a state, and a kernel-only API allows the
+ * drivers to manipulate that state. State transitions are atomic, and
+ * only some of them are allowed (see `enum wimax_st`).
+ *
+ * Most API calls will set the state automatically; in most cases
+ * drivers have to only report state changes due to external
+ * conditions.
+ *
+ * All API operations are 'atomic', serialized through a mutex in the
+ * `struct wimax_dev`.
+ *
+ * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
+ *
+ * The API is exported to user space using generic netlink (other
+ * methods can be added as needed).
+ *
+ * There is a Generic Netlink Family named "WiMAX", where interfaces
+ * supporting the WiMAX interface receive commands and broadcast their
+ * signals over a multicast group named "msg".
+ *
+ * Mapping to the source/destination interface is done by an interface
+ * index attribute.
+ *
+ * For user-to-kernel traffic (commands) we use a function call
+ * marshalling mechanism, where a message X with attributes A, B, C
+ * sent from user space to kernel space means executing the WiMAX API
+ * call wimax_X(A, B, C), sending the results back as a message.
+ *
+ * Kernel-to-user (notifications or signals) communication is sent
+ * over multicast groups. This allows to have multiple applications
+ * monitoring them.
+ *
+ * Each command/signal gets assigned it's own attribute policy. This
+ * way the validator will verify that all the attributes in there are
+ * only the ones that should be for each command/signal. Thing of an
+ * attribute mapping to a type+argumentname for each command/signal.
+ *
+ * If we had a single policy for *all* commands/signals, after running
+ * the validator we'd have to check "does this attribute belong in
+ * here"?  for each one. It can be done manually, but it's just easier
+ * to have the validator do that job with multiple policies. As well,
+ * it makes it easier to later expand each command/signal signature
+ * without affecting others and keeping the namespace more or less
+ * sane. Not that it is too complicated, but it makes it even easier.
+ *
+ * No state information is maintained in the kernel for each user
+ * space connection (the connection is stateless).
+ *
+ * TESTING FOR THE INTERFACE AND VERSIONING
+ *
+ * If network interface X is a WiMAX device, there will be a Generic
+ * Netlink family named "WiMAX X" and the device will present a
+ * "wimax" directory in it's network sysfs directory
+ * (/sys/class/net/DEVICE/wimax) [used by HAL].
+ *
+ * The inexistence of any of these means the device does not support
+ * this WiMAX API.
+ *
+ * By querying the generic netlink controller, versioning information
+ * and the multicast groups available can be found. Applications using
+ * the interface can either rely on that or use the generic netlink
+ * controller to figure out which generic netlink commands/signals are
+ * supported.
+ *
+ * NOTE: this versioning is a last resort to avoid hard
+ *    incompatibilities. It is the intention of the design of this
+ *    stack not to introduce backward incompatible changes.
+ *
+ * The version code has to fit in one byte (restrictions imposed by
+ * generic netlink); we use `version / 10` for the major version and
+ * `version % 10` for the minor. This gives 9 minors for each major
+ * and 25 majors.
+ *
+ * The version change protocol is as follow:
+ *
+ * - Major versions: needs to be increased if an existing message/API
+ *   call is changed or removed. Doesn't need to be changed if a new
+ *   message is added.
+ *
+ * - Minor version: needs to be increased if new messages/API calls are
+ *   being added or some other consideration that doesn't impact the
+ *   user-kernel interface too much (like some kind of bug fix) and
+ *   that is kind of left up in the air to common sense.
+ *
+ * User space code should not try to work if the major version it was
+ * compiled for differs from what the kernel offers. As well, if the
+ * minor version of the kernel interface is lower than the one user
+ * space is expecting (the one it was compiled for), the kernel
+ * might be missing API calls; user space shall be ready to handle
+ * said condition. Use the generic netlink controller operations to
+ * find which ones are supported and which not.
+ *
+ * libwimaxll:wimaxll_open() takes care of checking versions.
+ *
+ * THE OPERATIONS:
+ *
+ * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
+ * for clarity. The parts needed for an operation are:
+ *
+ *  - a function pointer in `struct wimax_dev`: optional, as the
+ *    operation might be implemented by the stack and not by the
+ *    driver.
+ *
+ *    All function pointers are named wimax_dev->op_*(), and drivers
+ *    must implement them except where noted otherwise.
+ *
+ *  - When exported to user space, a `struct nla_policy` to define the
+ *    attributes of the generic netlink command and a `struct genl_ops`
+ *    to define the operation.
+ *
+ * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
+ * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
+ * include/linux/wimax.h; this file is intended to be cloned by user
+ * space to gain access to those declarations.
+ *
+ * A few caveats to remember:
+ *
+ *  - Need to define attribute numbers starting in 1; otherwise it
+ *    fails.
+ *
+ *  - the `struct genl_family` requires a maximum attribute id; when
+ *    defining the `struct nla_policy` for each message, it has to have
+ *    an array size of WIMAX_GNL_ATTR_MAX+1.
+ *
+ * The op_*() function pointers will not be called if the wimax_dev is
+ * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is:
+ *
+ * - op_reset: can be called at any time after wimax_dev_add() has
+ *   been called.
+ *
+ * THE PIPE INTERFACE:
+ *
+ * This interface is kept intentionally simple. The driver can send
+ * and receive free-form messages to/from user space through a
+ * pipe. See drivers/net/wimax/op-msg.c for details.
+ *
+ * The kernel-to-user messages are sent with
+ * wimax_msg(). user-to-kernel messages are delivered via
+ * wimax_dev->op_msg_from_user().
+ *
+ * RFKILL:
+ *
+ * RFKILL support is built into the wimax_dev layer; the driver just
+ * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
+ * the hardware or software RF kill switches. When the stack wants to
+ * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
+ * which the driver implements.
+ *
+ * User space can set the software RF Kill switch by calling
+ * wimax_rfkill().
+ *
+ * The code for now only supports devices that don't require polling;
+ * If the device needs to be polled, create a self-rearming delayed
+ * work struct for polling or look into adding polled support to the
+ * WiMAX stack.
+ *
+ * When initializing the hardware (_probe), after calling
+ * wimax_dev_add(), query the device for it's RF Kill switches status
+ * and feed it back to the WiMAX stack using
+ * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
+ * report it as ON.
+ *
+ * NOTE: the wimax stack uses an inverted terminology to that of the
+ * RFKILL subsystem:
+ *
+ *  - ON: radio is ON, RFKILL is DISABLED or OFF.
+ *  - OFF: radio is OFF, RFKILL is ENABLED or ON.
+ *
+ * MISCELLANEOUS OPS:
+ *
+ * wimax_reset() can be used to reset the device to power on state; by
+ * default it issues a warm reset that maintains the same device
+ * node. If that is not possible, it falls back to a cold reset
+ * (device reconnect). The driver implements the backend to this
+ * through wimax_dev->op_reset().

+/**
+ * struct wimax_dev - Generic WiMAX device
+ *
+ * @net_dev: [fill] Pointer to the &struct net_device this WiMAX
+ *     device implements.
+ *
+ * @op_msg_from_user: [fill] Driver-specific operation to
+ *     handle a raw message from user space to the driver. The
+ *     driver can send messages to user space using with
+ *     wimax_msg_to_user().
+ *

+ *     userspace (or any other agent) requesting the WiMAX device to
+ *     change the RF Kill software switch (WIMAX_RF_ON or
+ *     WIMAX_RF_OFF).
+ *     If such hardware support is not present, it is assumed the
+ *     radio cannot be switched off and it is always on (and the stack
+ *     will error out when trying to switch it off). In such case,
+ *     this function pointer can be left as NULL.
+ *
+ * @op_reset: [fill] Driver specific operation to reset the
+ *     device.
+ *     This operation should always attempt first a warm reset that
+ *     does not disconnect the device from the bus and return 0.
+ *     If that fails, it should resort to some sort of cold or bus
+ *     reset (even if it implies a bus disconnection and device
+ *     dissapearance). In that case, -ENODEV should be returned to
+ *     indicate the device is gone.
+ *     This operation has to be synchronous, and return only when the
+ *     reset is complete. In case of having had to resort to bus/cold
+ *     reset implying a device disconnection, the call is allowed to
+ *     return inmediately.
+ *     NOTE: wimax_dev->mutex is NOT locked when this op is being
+ *     called; however, wimax_dev->mutex_reset IS locked to ensure
+ *     serialization of calls to wimax_reset().
+ *     See wimax_reset()'s documentation.
+ *
+ * @name: [fill] A way to identify this device. We need to register a
+ *     name with many subsystems (rfkill, workqueue creation, etc).
+ *     We can't use the network device name as that
+ *     might change and in some instances we don't know it yet (until
+ *     we don't call register_netdev()). So we generate an unique one
+ *     using the driver name and device bus id, place it here and use
+ *     it across the board. Recommended naming:
+ *     DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
+ *
+ * @id_table_node: [private] link to the list of wimax devices kept by
+ *     id-table.c. Protected by it's own spinlock.
+ *
+ * @mutex: [private] Serializes all concurrent access and execution of
+ *     operations.
+ *
+ * @mutex_reset: [private] Serializes reset operations. Needs to be a
+ *     different mutex because as part of the reset operation, the
+ *     driver has to call back into the stack to do things such as
+ *     state change, that require wimax_dev->mutex.
+ *
+ * @state: [private] Current state of the WiMAX device.
+ *
+ * @rfkill: [private] integration into the RF-Kill infrastructure.
+ *
+ * @rf_sw: [private] State of the software radio switch (OFF/ON)
+ *
+ * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
+ *
+ * @debugfs_dentry: [private] Used to hook up a debugfs entry. This
+ *     shows up in the debugfs root as wimax\:DEVICENAME.
+ *
+ * Description:
+ * This structure defines a common interface to access all WiMAX
+ * devices from different vendors and provides a common API as well as
+ * a free-form device-specific messaging channel.
+ *
+ * Usage:
+ *  1. Embed a &struct wimax_dev at *the beginning* the network
+ *     device structure so that netdev_priv() points to it.
+ *
+ *  2. memset() it to zero
+ *
+ *  3. Initialize with wimax_dev_init(). This will leave the WiMAX
+ *     device in the %__WIMAX_ST_NULL state.
+ *
+ *  4. Fill all the fields marked with [fill]; once called
+ *     wimax_dev_add(), those fields CANNOT be modified.
+ *
+ *  5. Call wimax_dev_add() *after* registering the network
+ *     device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
+ *     state.
+ *     Protect the driver's net_device->open() against succeeding if
+ *     the wimax device state is lower than %WIMAX_ST_DOWN.
+ *
+ *  6. Select when the device is going to be turned on/initialized;
+ *     for example, it could be initialized on 'ifconfig up' (when the
+ *     netdev op 'open()' is called on the driver).
+ *
+ * When the device is initialized (at `ifconfig up` time, or right
+ * after calling wimax_dev_add() from _probe(), make sure the
+ * following steps are taken
+ *
+ *  a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
+ *     some API calls that shouldn't work until the device is ready
+ *     can be blocked.
+ *
+ *  b. Initialize the device. Make sure to turn the SW radio switch
+ *     off and move the device to state %WIMAX_ST_RADIO_OFF when
+ *     done. When just initialized, a device should be left in RADIO
+ *     OFF state until user space devices to turn it on.
+ *
+ *  c. Query the device for the state of the hardware rfkill switch
+ *     and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
+ *     as needed. See below.
+ *
+ * wimax_dev_rm() undoes before unregistering the network device. Once
+ * wimax_dev_add() is called, the driver can get called on the
+ * wimax_dev->op_* function pointers
+ *
+ * CONCURRENCY:
+ *
+ * The stack provides a mutex for each device that will disallow API
+ * calls happening concurrently; thus, op calls into the driver
+ * through the wimax_dev->op*() function pointers will always be
+ * serialized and *never* concurrent.
+ *
+ * For locking, take wimax_dev->mutex is taken; (most) operations in
+ * the API have to check for wimax_dev_is_ready() to return 0 before
+ * continuing (this is done internally).
+ *
+ * REFERENCE COUNTING:
+ *
+ * The WiMAX device is reference counted by the associated network
+ * device. The only operation that can be used to reference the device
+ * is wimax_dev_get_by_genl_info(), and the reference it acquires has
+ * to be released with dev_put(wimax_dev->net_dev).
+ *
+ * RFKILL:
+ *
+ * At startup, both HW and SW radio switchess are assumed to be off.
+ *
+ * At initialization time [after calling wimax_dev_add()], have the
+ * driver query the device for the status of the software and hardware
+ * RF kill switches and call wimax_report_rfkill_hw() and
+ * wimax_rfkill_report_sw() to indicate their state. If any is
+ * missing, just call it to indicate it is ON (radio always on).
+ *
+ * Whenever the driver detects a change in the state of the RF kill
+ * switches, it should call wimax_report_rfkill_hw() or
+ * wimax_report_rfkill_sw() to report it to the stack.

+/* Organization of SPD aka "XFRM rules"
+   ------------------------------------
+
+   Basic objects:
+   - policy rule, struct xfrm_policy (=SPD entry)
+   - bundle of transformations, struct dst_entry == struct xfrm_dst (=SA bundle)
+   - instance of a transformer, struct xfrm_state (=SA)
+   - template to clone xfrm_state, struct xfrm_tmpl
+
+   SPD is plain linear list of xfrm_policy rules, ordered by priority.
+   (To be compatible with existing pfkeyv2 implementations,
+   many rules with priority of 0x7fffffff are allowed to exist and
+   such rules are ordered in an unpredictable way, thanks to bsd folks.)
+
+   Lookup is plain linear search until the first match with selector.
+
+   If "action" is "block", then we prohibit the flow, otherwise:
+   if "xfrms_nr" is zero, the flow passes untransformed. Otherwise,
+   policy entry has list of up to XFRM_MAX_DEPTH transformations,
+   described by templates xfrm_tmpl. Each template is resolved
+   to a complete xfrm_state (see below) and we pack bundle of transformations
+   to a dst_entry returned to requestor.
+
+   dst -. xfrm  .-> xfrm_state #1
+    |---. child .-> dst -. xfrm .-> xfrm_state #2
+                     |---. child .-> dst -. xfrm .-> xfrm_state #3
+                                      |---. child .-> NULL
+
+   Bundles are cached at xrfm_policy struct (field ->bundles).
+
+
+   Resolution of xrfm_tmpl
+   -----------------------
+   Template contains:
+   1. ->mode		Mode: transport or tunnel
+   2. ->id.proto	Protocol: AH/ESP/IPCOMP
+   3. ->id.daddr	Remote tunnel endpoint, ignored for transport mode.
+      Q: allow to resolve security gateway?
+   4. ->id.spi          If not zero, static SPI.
+   5. ->saddr		Local tunnel endpoint, ignored for transport mode.
+   6. ->algos		List of allowed algos. Plain bitmask now.
+      Q: ealgos, aalgos, calgos. What a mess...
+   7. ->share		Sharing mode.
+      Q: how to implement private sharing mode? To add struct sock* to
+      flow id?
+
+   Having this template we search through SAD searching for entries
+   with appropriate mode/proto/algo, permitted by selector.
+   If no appropriate entry found, it is requested from key manager.
+
+   PROBLEMS:
+   Q: How to find all the bundles referring to a physical path for
+      PMTU discovery? Seems, dst should contain list of all parents...
+      and enter to infinite locking hierarchy disaster.
+      No! It is easier, we will not search for them, let them find us.
+      We add genid to each dst plus pointer to genid of raw IP route,
+      pmtu disc will update pmtu on raw IP route and increase its genid.
+      dst_check() will see this for top level and trigger resyncing
+      metrics. Plus, it will be made via sk->sk_dst_cache. Solved.

+ * @start_conn:		set connection to be operational
+ * @stop_conn:		suspend/recover/terminate connection

+   History:
+    Started: Aug 9 by Lawrence Foard (entropy@world.std.com), to allow user
+     process control of SCSI devices.
+    Development Sponsored by Killy Corp. NY NY
+Original driver (sg.h):
+*       Copyright (C) 1992 Lawrence Foard
+Version 2 and 3 extensions to driver:
+*       Copyright (C) 1998 - 2006 Douglas Gilbert
+
+    Version: 3.5.34 (20060920)
+    This version is for 2.6 series kernels.
+
+    For a full changelog see http://www.torque.net/sg
+
+Map of SG verions to the Linux kernels in which they appear:
+       ----------        ----------------------------------
+       original          all kernels < 2.2.6
+       2.1.40            2.2.20
+       3.0.x             optional version 3 sg driver for 2.2 series
+       3.1.17++          2.4.0++
+       3.5.30++          2.6.0++
+
+Major new features in SG 3.x driver (cf SG 2.x drivers)
+	- SG_IO ioctl() combines function if write() and read()
+	- new interface (sg_io_hdr_t) but still supports old interface
+	- scatter/gather in user space, direct IO, and mmap supported
+
+ The normal action of this driver is to use the adapter (HBA) driver to DMA
+ data into kernel buffers and then use the CPU to copy the data into the 
+ user space (vice versa for writes). That is called "indirect" IO due to 
+ the double handling of data. There are two methods offered to remove the
+ redundant copy: 1) direct IO and 2) using the mmap() system call to map
+ the reserve buffer (this driver has one reserve buffer per fd) into the
+ user space. Both have their advantages.
+ In terms of absolute speed mmap() is faster. If speed is not a concern, 
+ indirect IO should be fine. Read the documentation for more information.
+
+ ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
+         'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
+         That attribute is 0 by default. **
+ 
+ Historical note: this SCSI pass-through driver has been known as "sg" for 
+ a decade. In broader kernel discussions "sg" is used to refer to scatter
+ gather techniques. The context should clarify which "sg" is referred to.
+
+ Documentation
+ =============
+ A web site for the SG device driver can be found at:
+	http://www.torque.net/sg  [alternatively check the MAINTAINERS file]
+ The documentation for the sg version 3 driver can be found at:
+ 	http://www.torque.net/sg/p/sg_v3_ho.html
+ This is a rendering from DocBook source [change the extension to "sgml"
+ or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
+ The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
+ For more information see http://www.torque.net/sg/sg_io.html
+
+ The older, version 2 documents discuss the original sg interface in detail:
+	http://www.torque.net/sg/p/scsi-generic.txt
+	http://www.torque.net/sg/p/scsi-generic_long.txt
+ Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
+
+ Utility and test programs are available at the sg web site. They are 
+ packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
+ (for the lk 2.2 series).

+ * Definitions of the OPL-3 registers.

+ * Copyright (c) by Jaroslav Kysela <perex@perex.cz>,
+ *                  Hannu Savolainen 1993-1996
+ *
+ *
+ *      The OPL-3 mode is switched on by writing 0x01, to the offset 5
+ *      of the right side.
+ *
+ *      Another special register at the right side is at offset 4. It contains
+ *      a bit mask defining which voices are used as 4 OP voices.
+ *
+ *      The percussive mode is implemented in the left side only.
+ *
+ *      With the above exceptions the both sides can be operated independently.
+ *      
+ *      A 4 OP voice can be created by setting the corresponding
+ *      bit at offset 4 of the right side.
+ *
+ *      For example setting the rightmost bit (0x01) changes the
+ *      first voice on the right side to the 4 OP mode. The fourth
+ *      voice is made inaccessible.
+ *
+ *      If a voice is set to the 2 OP mode, it works like 2 OP modes
+ *      of the original YM3812 (AdLib). In addition the voice can 
+ *      be connected the left, right or both stereo channels. It can
+ *      even be left unconnected. This works with 4 OP voices also.
+ *
+ *      The stereo connection bits are located in the FEEDBACK_CONNECTION
+ *      register of the voice (0xC0-0xC8). In 4 OP voices these bits are
+ *      in the second half of the voice.

+ */
+
+/* Some rough guidelines on accessing and updating grant-table entries
+ * in a concurrency-safe manner. For more information, Linux contains a
+ * reference implementation for guest OSes (arch/xen/kernel/grant_table.c).
+ *
+ * NB. WMB is a no-op on current-generation x86 processors. However, a
+ *     compiler barrier will still be required.
+ *
+ * Introducing a valid entry into the grant table:
+ *  1. Write ent->domid.
+ *  2. Write ent->frame:
+ *      GTF_permit_access:   Frame to which access is permitted.
+ *      GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ *                           frame, or zero if none.
+ *  3. Write memory barrier (WMB).
+ *  4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ *  This cannot be done directly. Request assistance from the domain controller
+ *  which can set a timeout on the use of a grant entry and take necessary
+ *  action. (NB. This is not yet implemented!).
+ *
+ * Invalidating an unused GTF_accept_transfer entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & GTF_transfer_committed). [*]
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *  [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
+ *      The guest must /not/ modify the grant entry until the address of the
+ *      transferred frame is written. It is safe for the guest to spin waiting
+ *      for this to occur (detect by observing GTF_transfer_completed in
+ *      ent->flags).
+ *
+ * Invalidating a committed GTF_accept_transfer entry:
+ *  1. Wait for (ent->flags & GTF_transfer_completed).
+ *
+ * Changing a GTF_permit_access from writable to read-only:
+ *  Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.
+ *
+ * Changing a GTF_permit_access from read-only to writable:
+ *  Use SMP-safe bit-setting instruction.

+	 *     source.
+	 *  3. Virtual interrupts ('events'). A domain can bind an event-channel
+	 *     port to a virtual interrupt source, such as the virtual-timer
+	 *     device or the emergency console.
+	 *
+	 * Event channels are addressed by a "port index". Each channel is

+	 *  1. PENDING -- notifies the domain that there is a pending notification
+	 *     to be processed. This bit is cleared by the guest.

+	 *     will cause an asynchronous upcall to be scheduled. This bit is only
+	 *     updated by the guest. It is read-only within Xen. If a channel
+	 *     becomes pending while the channel is masked then the 'edge' is lost
+	 *     (i.e., when the channel is unmasked, the guest must manually handle
+	 *     pending notifications as no upcall will be scheduled by Xen).
+	 *
+	 * To expedite scanning of pending notifications, any 0->1 pending
+	 * transition on an unmasked channel causes a corresponding bit in a
+	 * per-vcpu selector word to be set. Each bit in the selector covers a
