-Subject: HID: rmi: check sanity of the incoming report
-
-In the Dell XPS 13 9333, it appears that sometimes the bus get confused
-and corrupts the incoming data. It fills the input report with the
-sentinel value "ff". Synaptics told us that such behavior does not comes
-from the touchpad itself, so we filter out such reports here.
-
-Unfortunately, we can not simply discard the incoming data because they
-may contain useful information. Most of the time, the misbehavior is
-quite near the end of the report, so we can still use the valid part of
-it.

+Subject: [PATCH] Input: add driver for the Goodix touchpanel
+
+Add a driver for the Goodix touchscreen panel found in Onda v975w tablets.
+The driver is based off the Android driver gt9xx.c found in some Android
+code dumps, but now bears no resemblance to the original driver.
+
+The driver was tested on the aforementioned tablet.

-Subject: [PATCH] KEYS: Reinstate EPERM for a key type name beginning with a

-
-Reinstate the generation of EPERM for a key type name beginning with a '.' in
-a userspace call.  Types whose name begins with a '.' are internal only.
-
-The test was removed by:
-
-	commit a4e3b8d79a5c6d40f4a9703abf7fe3abcc6c3b8d
-	Author: Mimi Zohar <zohar@linux.vnet.ibm.com>
-	Date:   Thu May 22 14:02:23 2014 -0400
-	Subject: KEYS: special dot prefixed keyring name bug fix
-
-I think we want to keep the restriction on type name so that userspace can't
-add keys of a special internal type.
-
-Note that removal of the test causes several of the tests in the keyutils
-testsuite to fail.

-ThinkPad W530 the commit titled:
-"nouveau: Don't check acpi_video_backlight_support() before registering backlight"
-is also needed.

-Subject: [PATCH] drm/vmwgfx: Fix drm.h include
-
-The userspace drm.h include doesn't prefix the drm directory.  This can lead
-to compile failures as /usr/include/drm/ isn't in the standard gcc include
-paths.  Fix it to be <drm/drm.h>, which matches the rest of the driver drm
-header files that get installed into /usr/include/drm.
-
-Red Hat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1138759
-
-Fixes: 1d7a5cbf8f74e
-Reported-by: Jeffrey Bastian <jbastian@redhat.com>

+    arm64: [NOT FOR UPSTREAM] fix dma_ops for ACPI and PCI devices
+    
+    Commit 2189064795dc3fb4101e5:
+    
+      arm64: Implement set_arch_dma_coherent_ops() to replace bus notifiers
+    
+    removed the bus notifiers from dma-mapping.c. This patch
+    adds the notifier back for ACPI and PCI devices until a

+    acpi: add utility to test for device dma coherency
+    
+    ACPI 5.1 adds a _CCA object to indicate memory coherency
+    of a bus master device. It is an integer with zero meaning
+    non-coherent and one meaning coherent. This attribute may
+    be inherited from a parent device. It may also be missing
+    entirely, in which case, an architecture-specific default
+    is assumed.
+    
+    This patch adds a utility function to parse a device handle
+    (and its parents) for a _CCA object and return the coherency
+    attribute if found.

+    gpio: Support for unified device properties interface
+    
+    Some drivers need to deal with only firmware representation of its

+    model.
+    
+    In order to help device drivers to handle such firmware child nodes we
+    add dev[m]_get_named_gpiod_from_child() that takes a child firmware
+    node pointer as its second argument (the first one is the parent device
+    itself), finds the GPIO using whatever is the underlying firmware
+    method, and requests the GPIO properly.

+    gpio / ACPI: Add support for _DSD device properties
+    
+    With release of ACPI 5.1 and _DSD method we can finally name GPIOs (and
+    other things as well) returned by _CRS. Previously we were only able to
+    use integer index to find the corresponding GPIO, which is pretty error
+    prone if the order changes.
+    
+    With _DSD we can now query GPIOs using name instead of an integer index,
+    like the below example shows:
+    
+      // Bluetooth device with reset and shutdown GPIOs
+      Device (BTH)
+      {
+          Name (_HID, ...)
+    
+          Name (_CRS, ResourceTemplate ()
+          {
+              GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                      "\\_SB.GPO0", 0, ResourceConsumer) {15}
+              GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
+                      "\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
+          })
+    
+          Name (_DSD, Package ()
+          {
+              ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+              Package ()
+    	  {
+                  Package () {"reset-gpio", Package() {^BTH, 1, 1, 0 }},
+                  Package () {"shutdown-gpio", Package() {^BTH, 0, 0, 0 }},
+              }
+          })
+      }
+    
+    The format of the supported GPIO property is:
+    
+      Package () { "name", Package () { ref, index, pin, active_low }}
+    
+      ref - The device that has _CRS containing GpioIo()/GpioInt() resources,
+            typically this is the device itself (BTH in our case).
+      index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
+      pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
+      active_low - If 1 the GPIO is marked as active_low.
+    
+    Since ACPI GpioIo() resource does not have field saying whether it is
+    active low or high, the "active_low" argument can be used here. Setting
+    it to 1 marks the GPIO as active low.
+    
+    In our Bluetooth example the "reset-gpio" refers to the second GpioIo()
+    resource, second pin in that resource with the GPIO number of 31.
+    
+    This patch implements necessary support to gpiolib for extracting GPIOs
+    using _DSD device properties.

+
+    Driver core: Unified device properties interface for platform firmware
+    
+    Add a uniform interface by which device drivers can request device
+    properties from the platform firmware by providing a property name
+    and the corresponding data type.  The purpose of it is to help to
+    write portable code that won't depend on any particular platform
+    firmware interface.
+    
+    Three general helper functions, device_get_property(),
+    device_read_property() and device_read_property_array() are provided.
+    The first one allows the raw value of a given device property to be
+    accessed.  The remaining two allow the value of a numeric or string
+    property and multiple numeric or string values of one array
+    property to be acquired, respectively.  Static inline wrappers are also
+    provided for the various property data types that can be passed to
+    device_read_property() or device_read_property_array() for extra type
+    checking.
+    
+    In addition to that, new generic routines are provided for retrieving
+    properties from device description objects in the platform firmware
+    in case a device driver needs/wants to access properties of a child
+    object of a given device object.  There are cases in which there is
+    no struct device representation of such child objects and this
+    additional API is useful then.  Again, three functions are provided,
+    device_get_child_property(), device_read_child_property(),
+    device_read_child_property_array(), in analogy with device_get_property(),
+    device_read_property() and device_read_property_array() described above,
+    respectively, along with static inline wrappers for all of the propery
+    data types that can be used.  For all of them, the first argument is
+    a struct device pointer to the parent device object and the second
+    argument is a (void *) pointer to the child description provided by
+    the platform firmware (either ACPI or FDT).
+    
+    Finally, device_for_each_child_node() is added for iterating over
+    the children of the device description object associated with a
+    given device.
+    
+    The interface covers both ACPI and Device Trees.
+    
+    This change set includes material from Mika Westerberg and Aaron Lu.

+
+    ACPI: Add support for device specific properties
+    
+    Device Tree is used in many embedded systems to describe the system
+    configuration to the OS. It supports attaching properties or name-value
+    pairs to the devices it describe. With these properties one can pass
+    additional information to the drivers that would not be available
+    otherwise.
+    
+    ACPI is another configuration mechanism (among other things) typically
+    seen, but not limited to, x86 machines. ACPI allows passing arbitrary
+    data from methods but there has not been mechanism equivalent to Device
+    Tree until the introduction of _DSD in the recent publication of the
+    ACPI 5.1 specification.
+    
+    In order to facilitate ACPI usage in systems where Device Tree is
+    typically used, it would be beneficial to standardize a way to retrieve
+    Device Tree style properties from ACPI devices, which is what we do in
+    this patch.
+    
+    If a given device described in ACPI namespace wants to export properties it
+    must implement _DSD method (Device Specific Data, introduced with ACPI 5.1)
+    that returns the properties in a package of packages. For example:
+    
+    	Name (_DSD, Package () {
+    		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
+    		Package () {
+    			Package () {"name1", <VALUE1>},
+    			Package () {"name2", <VALUE2>},
+    			...
+    		}
+    	})
+    
+    The UUID reserved for properties is daffd814-6eba-4d8c-8a91-bc9bbf4aa301
+    and is documented in the ACPI 5.1 companion document called "_DSD
+    Implementation Guide" [1], [2].
+    
+    We add several helper functions that can be used to extract these
+    properties and convert them to different Linux data types.
+    
+    The ultimate goal is that we only have one device property API that
+    retrieves the requested properties from Device Tree or from ACPI
+    transparent to the caller.

+        Device (SATA0)
+        {

+            Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
+          })
+        }
+    
+    Since ATA driver should not require PCI support for ATA_ACPI,

+    ARM64 / ACPI: Parse FADT table to get PSCI flags for PSCI init
+    
+    There are two flags: PSCI_COMPLIANT and PSCI_USE_HVC. When set,
+    the former signals to the OS that the firmware is PSCI compliant.
+    The latter selects the appropriate conduit for PSCI calls by
+    toggling between Hypervisor Calls (HVC) and Secure Monitor Calls
+    (SMC).
+    
+    FADT table contains such information, parse FADT to get the flags
+    for PSCI init. Since ACPI 5.1 doesn't support self defined PSCI
+    function IDs, which means that only PSCI 0.2+ is supported in ACPI.
+    
+    At the same time, only ACPI 5.1 or higher verison supports PSCI,
+    and FADT Major.Minor version was introduced in ACPI 5.1, so we
+    will check the version and only parse FADT table with version >= 5.1.
+    
+    If firmware provides ACPI tables with ACPI version less than 5.1,
+    OS will be messed up with those information and have no way to init
+    smp and GIC, so disable ACPI if we get an FADT table with version
+    less that 5.1.

+
+    ACPI / table: Count matched and successfully parsed entries without specifying max entries
+    
+    It is very useful to traverse all available table entries without max
+    number of expected entries type. Current acpi_parse_entries()
+    implementation gives that feature but it does not count those entries,
+    it returns 0 instead, so fix it to count matched and successfully
+    entries and return it.
+    
+    NOTE: This change has no impact to x86 and ia64 archs since existing code
+    checks for error occurrence only (acpi_parse_entries(...,0) < 0).

+
+    ACPI / table: Add new function to get table entries
+    
+    The acpi_table_parse() function has a callback that
+    passes a pointer to a table_header. Add a new function
+    which takes this pointer and parses its entries. This
+    eliminates the need to re-traverse all the tables for
+    each call. e.g. as in acpi_table_parse_madt() which is
+    normally called after acpi_table_parse().

+    
+     ahci_xgene: fix the dma state machine lockup for the IDENTIFY DEVICE PIO mode command.
+    
+    added a workaround for X-Gene AHCI controller errata. This was done
+    for all ATA_CMD_ID_ATA commands. The errata also appears to affect
+    ATA_CMD_SMART commands as well. This was discovered when running

+    ATA_CMD_SMART commands which clears up the issues seen with smartd.

+    arm64: don't set READ_IMPLIES_EXEC for EM_AARCH64 ELF objects
+    
+    Message-id: <20140513222526.GC26038@redacted.bos.redhat.com>
+    Patchwork-id: 79789
+    O-Subject: [ACADIA PATCH] arm64: don't set READ_IMPLIES_EXEC for EM_AARCH64 ELF objects
+    Bugzilla: 1085528
+    
+    BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1085528
+    Upstream: submitted soon
+    
+    [Sadly this isn't (yet) sufficient... but it fixes at least one issue
+     here... cat /proc/$$/personality shows READ_IMPLIES_EXEC before. I'll
+     try to figure the rest out tomorrow.]
+    
+    Currently, we're accidentally ending up with executable stacks on
+    AArch64 when the ABI says we shouldn't be, and relying on glibc to fix
+    things up for us when we're loaded. However, SELinux will deny us
+    mucking with the stack, and hit us with execmem AVCs.
+    
+    The reason this is happening is somewhat complex:
+    
+    fs/binfmt_elf.c:load_elf_binary()
+     - initializes executable_stack = EXSTACK_DEFAULT implying the
+       architecture should make up its mind.
+     - does a pile of loading goo
+     - runs through the program headers, looking for PT_GNU_STACK
+       and setting (or unsetting) executable_stack if it finds it.
+    
+       This is our first problem, we won't generate these unless an
+       executable stack is explicitly requested.
+    
+     - more ELF loading goo
+     - sets whether we're a compat task or not (TIF_32BIT) based on compat.h
+     - for compat reasons (pre-GNU_STACK) checks if the READ_IMPLIES_EXEC
+       flag should be set for ancient toolchains
+    
+       Here's our second problem, we test if read_implies_exec based on
+       stk != EXSTACK_DISABLE_X, which is true since stk == EXSTACK_DEFAULT.
+    
+       So we set current->personality |= READ_IMPLIES_EXEC like a broken
+       legacy toolchain would want.
+    
+     - Now we call setup_arg_pages to set up the stack...
+    
+    fs/exec.c:setup_arg_pages()
+     - lots of magic happens here
+     - vm_flags gets initialized to VM_STACK_FLAGS
+    
+       Here's our third problem, VM_STACK_FLAGS on arm64 is
+       VM_DEFAULT_DATA_FLAG which tests READ_IMPLIES_EXEC and sets VM_EXEC
+       if it's true. So we end up with an executable stack mapping, since we
+       don't have executable_stack set (it's still EXSTACK_DEFAULT at this
+       point) to unset it anywhere.
+    
+    Bang. execstack AVC when the program starts running.
+    
+    The easiest way I can see to fix this is to test if we're a legacy task
+    and fix it up there. But that's not as simple as it sounds, because
+    the 32-bit ABI depends on what revision of the CPU we've enabled (not
+    that it matters since we're ARMv8...) Regardless, in the compat case,
+    set READ_IMPLIES_EXEC if we've found a GNU_STACK header which explicitly
+    requested it as in arch/arm/kernel/elf.c:arm_elf_read_implies_exec().

++ACPI device properties
++======================
++This document describes the format and interfaces of ACPI device
++properties as specified in "Device Properties UUID For _DSD" available
++here:
++
++http://www.uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf
++
++1. Introduction
++---------------
++In systems that use ACPI and want to take advantage of device specific
++properties, there needs to be a standard way to return and extract
++name-value pairs for a given ACPI device.
++
++An ACPI device that wants to export its properties must implement a
++static name called _DSD that takes no arguments and returns a package of
++packages:
++
++	Name (_DSD, Package () {
++		ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++		Package () {
++			Package () {"name1", <VALUE1>},
++			Package () {"name2", <VALUE2>}
++		}
++	})
++
++The UUID identifies contents of the following package. In case of ACPI
++device properties it is daffd814-6eba-4d8c-8a91-bc9bbf4aa301.
++
++In each returned package, the first item is the name and must be a string.
++The corresponding value can be a string, integer, reference, or package. If
++a package it may only contain strings, integers, and references.
++
++An example device where we might need properties is a device that uses
++GPIOs. In addition to the GpioIo/GpioInt resources the driver needs to
++know which GPIO is used for which purpose.
++
++To solve this we add the following ACPI device properties to the device:
++
++	Device (DEV0)
++	{
++		Name (_CRS, ResourceTemplate () {
++			GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
++				"\\_SB.PCI0.LPC", 0, ResourceConsumer) {0}
++			GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
++				"\\_SB.PCI0.LPC", 0, ResourceConsumer) {1}
++			...
++		})
++
++		Name (_DSD, Package () {
++			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++			Package () {
++				Package () {"reset-gpio", {^DEV0, 0, 0, 0}},
++				Package () {"shutdown-gpio", {^DEV0, 1, 0, 0}},
++			}
++		})
++	}
++
++Now the device driver can reference the GPIOs using names instead of
++using indexes.
++
++If there is an existing Device Tree binding for a device, it is expected
++that the same bindings are used with ACPI properties, so that the driver
++dealing with the device needs only minor modifications if any.
++
++2. Formal definition of properties
++----------------------------------
++The following chapters define the currently supported properties. For
++these there exists a helper function that can be used to extract the
++property value.
++
++2.1 Integer types
++-----------------
++ACPI integers are always 64-bit. However, for drivers the full range is
++typically not needed so we provide a set of functions which convert the
++64-bit integer to a smaller Linux integer type.
++
++An integer property looks like this:
++
++	Package () {"i2c-sda-hold-time-ns", 300},
++	Package () {"clock-frequency", 400000},
++
++To read a property value, use a unified property accessor as shown
++below:
++
++	u32 val;
++	int ret;
++
++	ret = device_property_read_u32(dev, "clock-frequency", &val);
++	if (ret)
++		/* Handle error */
++
++The function returns 0 if the property is copied to 'val' or negative
++errno if something went wrong (or the property does not exist).
++
++2.2 Integer arrays
++------------------
++An integer array is a package holding only integers. Arrays can be used to
++represent different things like Linux input key codes to GPIO mappings, pin
++control settings, dma request lines, etc.
++
++An integer array looks like this:
++
++	Package () {
++		"max8952,dvs-mode-microvolt",
++		Package () {
++			1250000,
++			1200000,
++			1050000,
++			950000,
++		}
++	}
++
++The above array property can be accessed like:
++
++	u32 voltages[4];
++	int ret;
++
++	ret = device_property_read_u32_array(dev, "max8952,dvs-mode-microvolt",
++					     voltages, ARRAY_SIZE(voltages));
++	if (ret)
++		/* Handle error */
++
++
++All functions copy the resulting values cast to a requested type to the
++caller supplied array. If you pass NULL in the value pointer ('voltages' in
++this case), the function returns number of items in the array. This can be
++useful if caller does not know size of the array beforehand.
++
++2.3 Strings
++-----------
++String properties can be used to describe many things like labels for GPIO
++buttons, compability ids, etc.
++
++A string property looks like this:
++
++	Package () {"pwm-names", "backlight"},
++	Package () {"label", "Status-LED"},
++
++You can use device_property_read_string() to extract strings:
++
++	const char *val;
++	int ret;
++
++	ret = device_property_read_string(dev, "label", &val);
++	if (ret)
++		/* Handle error */
++
++Note that the function does not copy the returned string but instead the
++value is modified to point to the string property itself.
++
++The memory is owned by the associated ACPI device object and released
++when it is removed. The user need not free the associated memory.
++
++2.4 String arrays
++-----------------
++String arrays can be useful in describing a list of labels, names for
++DMA channels, etc.
++
++A string array property looks like this:
++
++	Package () {"dma-names", Package () {"tx", "rx", "rx-tx"}},
++	Package () {"clock-output-names", Package () {"pll", "pll-switched"}},
++
++And these can be read in similar way that the integer arrrays:
++
++	const char *dma_names[3];
++	int ret;
++
++	ret = device_property_read_string_array(dev, "dma-names", dma_names,
++						ARRAY_SIZE(dma_names));
++	if (ret)
++		/* Handle error */
++
++The memory management rules follow what is specified for single strings.
++Specifically the returned pointers should be treated as constant and not to
++be freed. That is done automatically when the correspondig ACPI device
++object is released.
++
++2.5 Object references
++---------------------
++An ACPI object reference is used to refer to some object in the
++namespace. For example, if a device has dependencies with some other
++object, an object reference can be used.
++
++An object reference looks like this:
++
++	Package () {"dev0", \_SB.DEV0},
++
++At the time of writing this, there is no unified device_property_* accessor
++for references so one needs to use the following ACPI helper function:
++
++	int acpi_dev_get_property_reference(struct acpi_device *adev,
++					    const char *name,
++					    const char *size_prop, int index,
++					    struct acpi_reference_args *args);
++
++The referenced ACPI device is returned in args->adev if found.
++
++In addition to simple object references it is also possible to have object
++references with arguments. These are represented in ASL as follows:
++
++	Device (\_SB.PCI0.PWM)
++	{
++		Name (_DSD, Package () {
++			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++			Package () {
++				Package () {"#pwm-cells", 2}
++			}
++		})
++	}
++
++	Device (\_SB.PCI0.BL)
++	{
++		Name (_DSD, Package () {
++			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++			Package () {
++				Package () {
++					"pwms",
++					Package () {
++						\_SB.PCI0.PWM, 0, 5000000,
++						\_SB.PCI0.PWM, 1, 4500000,
++					}
++				}
++			}
++		})
++	}
++
++In the above example, the referenced device declares a property that
++returns the number of expected arguments (here it is "#pwm-cells"). If
++no such property is given we assume that all the integers following the
++reference are arguments.
++
++In the above example PWM device expects 2 additional arguments. This
++will be validated by the ACPI property core.
++
++The additional arguments must be integers. Nothing else is supported.
++
++It is possible, as in the above example, to have multiple references
++with varying number of integer arguments. It is up to the referenced
++device to declare how many arguments it expects. The 'index' parameter
++selects which reference is returned.
++
++One can use acpi_dev_get_property_reference() as well to extract the
++information in additional parameters:
++
++	struct acpi_reference_args args;
++	struct acpi_device *adev = /* this will point to the BL device */
++	int ret;
++
++	/* extract the first reference */
++	acpi_dev_get_property_reference(adev, "pwms", "#pwm-cells", 0, &args);
++
++	BUG_ON(args.nargs != 2);
++	BUG_ON(args.args[0] != 0);
++	BUG_ON(args.args[1] != 5000000);
++
++	/* extract the second reference */
++	acpi_dev_get_property_reference(adev, "pwms", "#pwm-cells", 1, &args);
++
++	BUG_ON(args.nargs != 2);
++	BUG_ON(args.args[0] != 1);
++	BUG_ON(args.args[1] != 4500000);
++
++In addition to arguments, args.adev now points to the ACPI device that
++corresponds to \_SB.PCI0.PWM.
++
++It is intended that this function is not used directly but instead
++subsystems like pwm implement their ACPI support on top of this function
++in such way that it is hidden from the client drivers, such as via
++pwm_get().
++
++3. Device property hierarchies
++------------------------------
++Devices are organized in a tree within the Linux kernel. It follows that
++the configuration data would also be hierarchical. In order to reach
++equivalence with Device Tree, the ACPI mechanism must also provide some
++sort of tree-like representation. Fortunately, the ACPI namespace is
++already such a structure.
++
++For example, we could have the following device in ACPI namespace. The
++KEYS device is much like gpio_keys_polled.c in that it includes "pseudo"
++devices for each GPIO:
++
++	Device (KEYS)
++	{
++		Name (_CRS, ResourceTemplate () {
++			GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
++				"\\_SB.PCI0.LPC", 0, ResourceConsumer) {0}
++			GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
++				"\\_SB.PCI0.LPC", 0, ResourceConsumer) {1}
++			...
++		})
++
++		// "pseudo" devices declared under the parent device
++		Device (BTN0) {
++			Name (_DSD, Package () {
++				ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++				Package () {
++					Package () {"label", "minnow_btn0"}
++					Package () {"gpios", Package () {^KEYS, 0, 0, 1}}
++				}
++			})
++		}
++
++		Device (BTN1) {
++			Name (_DSD, Package () {
++				ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++				Package () {
++					Package () {"label", "minnow_btn1"}
++					Package () {"gpios", Package () {^KEYS, 1, 0, 1}}
++				}
++			})
++		}
++	}
++
++We can extract the above in gpio_keys_polled.c like:
++
++	static int gpio_keys_polled_create_button(struct device *dev, void *child,
++						  void *data)
++	{
++		struct button_data *bdata = data;
++		const char *label = NULL;
++
++		/*
++		 * We need to use device_child_ variant here to access
++		 * properties of the child.
++		 */
++		device_child_property_read_string(dev, child, "label", &label);
++		/* and so on */
++	}
++
++	static void gpio_keys_polled_probe(struct device *dev)
++	{
++		/* Properties for the KEYS device itself */
++		device_property_read(dev, ...);
++
++		/*
++		 * Iterate over button devices and extract their
++		 * firmware configuration.
++		 */
++		ret = device_for_each_child_node(dev, gpio_keys_polled_create_button,
++						 &bdata);
++		if (ret)
++			/* Handle error */
++	}
++
++Note that you still need proper error handling which is omitted in the
++above example.
++
++4. Existing Device Tree enabled drivers
++---------------------------------------
++At the time of writing this, there are ~250 existing DT enabled drivers.
++Allocating _HID/_CID for each would not be feasible. To make sure that
++those drivers can still be used on ACPI systems, we provide an
++alternative way to get these matched.
++
++There is a special _HID "PRP0001" which means that use the DT bindings
++for matching this device to a driver. The driver needs to have
++.of_match_table filled in even when !CONFIG_OF.
++
++An example device would be leds that can be controlled via GPIOs. This
++is represented as "leds-gpio" device and looks like this in the ACPI
++namespace:
++
++	Device (LEDS)
++	{
++		Name (_DSD, Package () {
++			ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
++			Package () {
++				Package () {"compatible", Package () {"gpio-leds"}},
++			}
++		})
++		...
++	}
++
++In order to get the existing drivers/leds/leds-gpio.c bound to this
++device, we take advantage of "PRP0001":
++
++	/* Following already exists in the driver */
++	static const struct of_device_id of_gpio_leds_match[] = {
++		{ .compatible = "gpio-leds", },
++		{},
 +	};
++	MODULE_DEVICE_TABLE(of, of_gpio_leds_match);
 +
-+Board specific DT Entry:
-+	&pcie0 {
-+		status = "ok";
++	/* This we add to the driver to get it probed */
++	static const struct acpi_device_id acpi_gpio_leds_match[] = {
++		{ "PRP0001" }, /* Device Tree shoehorned into ACPI */
++		{},
++	};
++	MODULE_DEVICE_TABLE(acpi, acpi_gpio_leds_match);
++
++	static struct platform_driver gpio_led_driver = {
++		.driver = {
++			/*
++			 * No of_match_ptr() here because we want this
++			 * table to be visible even when !CONFIG_OF to
++			 * match against "compatible" in _DSD.
++			 */
++			.of_match_table = of_gpio_leds_match,
++			.acpi_match_table = acpi_gpio_leds_match,
++		},
 +	};

++ACPI on ARMv8 Servers
++---------------------
++
++ACPI can be used for ARMv8 general purpose servers designed to follow
++the SBSA specification (currently available to people with an ARM login at
++http://silver.arm.com).
++
++The kernel will implement minimum ACPI version is 5.1 + errata as released by
++the UEFI Forum, which is available at <http://www.uefi.org/acpi/specs>.
++
++If the machine does not meet the requirements of the SBSA, or cannot be
++described in the required ACPI specifications then it is likely that Device Tree
++(DT) is more suitable for the hardware.
++
++Relationship with Device Tree
++-----------------------------
++
++ACPI support in drivers and subsystems for ARMv8 should never be mutually
++exclusive with DT support at compile time.
++
++At boot time the kernel will only use one description method depending on
++parameters passed from the bootloader (including kernel bootargs).
++
++Regardless of whether DT or ACPI is used, the kernel must always be capable
++of booting with either scheme (in kernels with both schemes enabled at compile
++time).
++
++When booting using ACPI tables the /chosen node in DT will still be parsed
++to extract the kernel command line and initrd path. No other section of
++the DT will be used.
++
++Booting using ACPI tables
++-------------------------
++
++Currently, the only defined method to pass ACPI tables to the kernel on ARMv8
++is via the UEFI system configuration table.
++
++The UEFI implementation MUST set the ACPI_20_TABLE_GUID to point to the
++RSDP table (the table with the ACPI signature "RSD PTR ").
++
++The pointer to the RSDP table will be retrieved from EFI by the ACPI core.
++
++Processing of ACPI tables may be disabled by passing acpi=off on the kernel
++command line.
++
++DO use an XSDT; RSDTs are deprecated and should not be used on arm64. They
++only allow for 32-bit addresses.
++
++DO NOT use the 32-bit address fields in the FADT; they are deprecated. The
++64-bit alternatives MUST be used.
++
++The minimum set of tables MUST include RSDP, XSDT, FACS, FADT, DSDT, MADT
++and GTDT. If PCI is used the MCFG table MUST also be present.
++
++ACPI Detection
++--------------
++
++Drivers should determine their probe() type by checking for ACPI_HANDLE,
++or .of_node, or other information in the device structure. This is
++detailed further in the "Driver Recommendations" section.
++
++In non-driver code If the presence of ACPI needs to be detected at runtime,
++then check the value of acpi_disabled. If CONFIG_ACPI is not set,
++acpi_disabled will always be 1.
++
++Device Enumeration
++------------------
++
++Device descriptions in ACPI should use standard recognized ACPI interfaces.
++These are far simpler than the information provided via Device Tree. Drivers
++should take into account this simplicity and work with sensible defaults.
++
++On no account should a Device Tree attempt to be replicated in ASL using such
++constructs as Name(KEY0, "Value1") type constructs. Additional driver specific
++data should be represented with the appropriate _DSD (ACPI Section 6.2.5)
++structure. _DSM (ACPI Section 9.14.1) should only be used if _DSD cannot
++represent the data required.
++
++This data should be rare and not OS specific. For x86 ACPI has taken to
++identifying itself as Windows because it was found that only one path was
++routinely tested. For ARMv8 it would be preferable to have only one well
++tested path.
++
++_DSD covers more than the generic server case and care should be taken not to
++replicate highly specific embedded behaviour from DT into generic servers.
++
++Common _DSD bindings should be submitted to ASWG to be included in the
++document :-
++
++http://www.uefi.org/sites/default/files/resources/_DSD-implementation-guide-toplevel.htm
++
++If these bindings are mirrored from DT care should be taken to ensure they are
++reviewed as DT bindings before submission to limit divergance in bindings.
++
++Programmable Power Control Resources
++------------------------------------
++
++Programmable power control resources include such resources as voltage/current
++providers (regulators) and clock sources.
++
++For power control of these resources they should be represented with Power
++Resource Objects (ACPI Section 7.1). The ACPI core will then handle correctly
++enabling/disabling of resources as they are needed.
++
++The ACPI 5.1 specification does not contain any standard binding for these
++objects to enable programmable levels or rates so this should be avoided if
++possible and the resources set to appropriate levels by the firmware. If this is
++not possible then any manipulation should be abstracted in ASL.
++
++Each device in ACPI has D-states and these can be controlled through
++the optional methods _PS0..._PS3 where _PS0 is full on and _PS3 is full off.
++
++If either _PS0 or _PS3 is implemented, then the other method must also be
++implemented.
++
++If a device requires usage or setup of a power resource when on, the ASL
++should organize that it is allocated/enabled using the _PS0 method.
++
++Resources allocated/enabled in the _PS0 method should be disabled/de-allocated
++in the _PS3 method.
++
++Such code in _PS? methods will of course be very platform specific but
++should allow the driver to operate the device without special non-standard
++values being read from ASL. Further, abstracting the use of these resources
++allows hardware revisions without requiring updates to the kernel.
++
++Clocks
++------
++
++Like clocks that are part of the power resources there is no standard way
++to represent a clock tree in ACPI 5.1 in a similar manner to how it is
++described in DT.
++
++Devices affected by this include things like UARTs, SoC driven LCD displays,
++etc.
++
++The firmware (for example, UEFI) should initialize these clocks to fixed working
++values before the kernel is executed.
++
++Driver Recommendations
++----------------------
++
++DO NOT remove any FDT handling when adding ACPI support for a driver. Different
++systems may use the same device.
++
++DO try and keep complex sections of ACPI and DT functionality separate. This
++may mean a patch to break out some complex DT to another function before
++the patch to add ACPI. This may happen in other functions but is most likely
++in probe function. This gives a clearer flow of data for reviewing driver
++source.
++
++probe() :-
++
++static int device_probe_dt(struct platform_device *pdev)
++{
++	/* DT specific functionality */
++	...
++}
++
++static int device_probe_acpi(struct platform_device *pdev)
++{
++	/* ACPI specific functionality */
++	...
++}
++
++static int device_probe(stuct platform_device *pdev)
++{
++	...
++	struct device_node node = pdev->dev.of_node;
++	...
++
++	if (node)
++		ret = device_probe_dt(pdev);
++	else if (ACPI_HANDLE(&pdev->dev))
++		ret = device_probe_acpi(pdev);
++	else
++		/* other initialization */
++		...
++	/* Continue with any generic probe operations */
++	...
++}
++
++DO keep the MODULE_DEVICE_TABLE entries together in the driver to make it clear
++the different names the driver is probed for, both from DT and from ACPI.
++
++module device tables :-
++
++static struct of_device_id virtio_mmio_match[] = {
++        { .compatible = "virtio,mmio", },
++        { }
++};

++static const struct acpi_device_id virtio_mmio_acpi_match[] = {
++        { "LNRO0005", },
++        { }
++};
++MODULE_DEVICE_TABLE(acpi, virtio_mmio_acpi_match);
++
++ASWG
++----
++
++The following areas are not yet well defined for ARM in the current ACPI
++specification and are expected to be worked through in the UEFI ACPI
++Specification Working Group (ASWG) <http://www.uefi.org/workinggroups>.
++Participation in this group is open to all UEFI members.
++
++	- ACPI based CPU topology
++	- ACPI based Power management
++	- CPU idle control based on PSCI
++	- CPU performance control (CPPC)
++	- ACPI based SMMU
++	- ITS support for GIC in MADT
++
++No code shall be accepted into the kernel unless it complies with the released
++standards from UEFI ASWG. If there are features missing from ACPI to make it
++function on a platform, ECRs should be submitted to ASWG and go through the
++approval process.

-Subject: [PATCH] psmouse: Add support for detecting FocalTech PS/2 touchpads
-
-The Asus X450 and X550 laptops use a PS/2 touchpad from a new manufacturer
-called FocalTech:
-
-https://bugzilla.kernel.org/show_bug.cgi?id=77391
-https://bugzilla.redhat.com/show_bug.cgi?id=1110011
-
-The protocol for these devices is not known at this time, but even without
-knowing the protocol they need some special handling. They get upset by some
-of our other PS/2 device probing, and once upset generate random mouse events
-making things unusable even with an external mouse.
-
-This patch adds detection of these devices based on their pnp ids, and when
-they are detected, treats them as a bare ps/2 mouse. Doing things this way
-they at least work in their ps/2 mouse emulation mode.

+Subject: [PATCH] sched: Remove lockdep check in sched_move_task()
+
+sched_move_task() is the only interface to change sched_task_group:
+cpu_cgrp_subsys methods and autogroup_move_group() use it.
+
+Everything is synchronized by task_rq_lock(), so cpu_cgroup_attach()
+is ordered with other users of sched_move_task(). This means we do no
+need RCU here: if we've dereferenced a tg here, the .attach method
+hasn't been called for it yet.
+
+Thus, we should pass "true" to task_css_check() to silence lockdep
+warnings.
+
+Fixes: eeb61e53ea19 ("sched: Fix race between task_group and sched_task_group")

+Subject: [PATCH] virtio_console: move early VQ enablement
+
+Commit f5866db6 (virtio_console: enable VQs early) tried to make
+sure that DRIVER_OK was set when virtio_console started using its
+virtqueues. Doing this in add_port(), however, means that we try
+to set DRIVER_OK again when when a port is dynamically added after
+the probe function is done.
+
+Let's move virtio_device_ready() to the probe function just before
+trying to use the virtqueues instead. This is fine as nothing can
+fail inbetween.
