* Suspend-related patches for 2.6.27Rafael J. Wysocki2008-06-122-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI PM: Add possibility to change suspend sequence There are some systems out there that don't work correctly with our current suspend/hibernation code ordering. Provide a workaround for these systems allowing them to pass 'acpi_sleep=old_ordering' in the kernel command line so that it will use the pre-ACPI 2.0 ("old") suspend code ordering. Unfortunately, this requires us to add a platform hook to the resuming of devices for recovering the platform in case one of the device drivers' .suspend() routines returns error code. Namely, ACPI 1.0 specifies that _PTS should be called before suspending devices, but _WAK still should be called before resuming them in order to undo the changes made by _PTS. However, if there is an error during suspending devices, they are automatically resumed without returning control to the PM core, so the _WAK has to be called from within device_resume() in that cases. The patch also reorders and refactors the ACPI suspend/hibernation code to avoid duplication as far as reasonably possible. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | Get rid of a superfluous acpi_pm_device_sleep_state() parameter. The only legitimate value of that parameter must be derived from the first parameter, which is what all the callers already do. (However, this does not address the fact that ACPI still doesn't set up those flags.)

* | PCI: introduce pci_slotAlex Chiang2008-06-102-11/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, /sys/bus/pci/slots/ only exposes hotplug attributes when a hotplug driver is loaded, but PCI slots have attributes such as address, speed, width, etc. that are not related to hotplug at all. Introduce pci_slot as the primary data structure and kobject model. Hotplug attributes described in hotplug_slot become a secondary structure associated with the pci_slot. This patch only creates the infrastructure that allows the separation of PCI slot attributes and hotplug attributes. In this patch, the PCI hotplug core remains the only user of this infrastructure, and thus, /sys/bus/pci/slots/ will still only become populated when a hotplug driver is loaded. A later patch in this series will add a second user of this new infrastructure and demonstrate splitting the task of exposing pci_slot attributes from hotplug_slot attributes. - Make pci_slot the primary sysfs entity. hotplug_slot becomes a subsidiary structure. o pci_create_slot() creates and registers a slot with the PCI core o pci_slot_add_hotplug() gives it hotplug capability - Change the prototype of pci_hp_register() to take the bus and slot number (on parent bus) as parameters. - Remove all the ->get_address methods since this functionality is now handled by pci_slot directly.

* | shpchp: check firmware before taking controlKenji Kaneshige2008-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the following problems of shpchp driver about getting hotplug control from firmware. - The shpchp driver must not control the hotplug controller if it fails to get control from the firmware. But current shpchp controls the hotplug controller regardless the result, because it doesn't check the return value of get_hp_hw_control_from_firmware(). - Current shpchp driver doesn't support _OSC. The pciehp driver already have the code for evaluating _OSC and OSHP and shpchp and pciehp can share it. So this patch move that code from pciehp to acpi_pcihp.c.

Modify the PM core to use 'struct pm_ops' and 'struct pm_ext_ops' objects, if defined, instead of the ->suspend(), ->resume(), ->suspend_late(), and ->resume_early() callbacks (the old callbacks will be considered as legacy and gradually phased out). The main purpose of doing this is to separate suspend (aka S2RAM and standby) callbacks from hibernation callbacks in such a way that the new callbacks won't take arguments and the semantics of each of them will be clearly specified. This has been requested for multiple times by many people, including Linus himself, and the reason is that within the current scheme if ->resume() is called, for example, it's difficult to say why it's been called (ie. is it a resume from RAM or from hibernation or a suspend/hibernation failure etc.?). The second purpose is to make the suspend/hibernation callbacks more flexible so that device drivers can handle more than they can within the current scheme. For example, some drivers may need to prevent new children of the device from being registered before their ->suspend() callbacks are executed or they may want to carry out some operations requiring the availability of some other devices, not directly bound via the parent-child relationship, in order to prepare for the execution of ->suspend(), etc. Ultimately, we'd like to stop using the freezing of tasks for suspend and therefore the drivers' suspend/hibernation code will have to take care of the handling of the user space during suspend/hibernation. That, in turn, would be difficult within the current scheme, without the new ->prepare() and ->complete() callbacks. Signed-off-by: Rafael J.

Also the patch introduces pci_fixup_resume_early and pci_fixup_suspend, which matches current device core callbacks (.suspend/.resume_early). TBD: Somebody knows why we need quirk resume should double check if a quirk should be called in resume or resume_early. I changed some per my understanding, but can't make sure I fixed all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 2.6.26, we added some support for send with invalidate work requests, including a device capability flag to indicate whether a device supports such requests. However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

Source code out there hard-codes a notion of what the _LINUX_CAPABILITY_VERSION #define means in terms of the semantics of the raw capability system calls capget() and capset(). Its unfortunate, but true. Since the confusing header file has been in a released kernel, there is software that is erroneously using 64-bit capabilities with the semantics of 32-bit compatibilities. These recently compiled programs may suffer corruption of their memory when sys_getcap() overwrites more memory than they are coded to expect, and the raising of added capabilities when using sys_capset(). As such, this patch does a number of things to clean up the situation for all. It 1. forces the _LINUX_CAPABILITY_VERSION define to always retain its legacy value. 2. adopts a new #define strategy for the kernel's internal implementation of the preferred magic. 3. deprecates v2 capability magic in favor of a new (v3) magic number. The functionality of v3 is entirely equivalent to v2, the only difference being that the v2 magic causes the kernel to log a "deprecated" warning so the admin can find applications that may be using v2 inappropriately. [User space code continues to be encouraged to use the libcap API which protects the application from details like this. libcap-2.10 is the first to support v3 capabilities.] Fixes issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=447518.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current __raw_write_can_lock macro tests whether the lock can be locked by checking if it is equal to 0x80000000, whereas the lock should be lockable if its value is 0 i.e. unlocked state is represented by 0. Hence the macro should test the value of lock against 0 and not 0x80000000. Signed-off-by: Surinder Pal Singh <srplsnh@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
