Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6

* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (72 commits)
  Revert "x86/PCI: ACPI based PCI gap calculation"
  PCI: remove unnecessary volatile in PCIe hotplug struct controller
  x86/PCI: ACPI based PCI gap calculation
  PCI: include linux/pm_wakeup.h for device_set_wakeup_capable
  PCI PM: Fix pci_prepare_to_sleep
  x86/PCI: Fix PCI config space for domains > 0
  Fix acpi_pm_device_sleep_wake() by providing a stub for CONFIG_PM_SLEEP=n
  PCI: Simplify PCI device PM code
  PCI PM: Introduce pci_prepare_to_sleep and pci_back_from_sleep
  PCI ACPI: Rework PCI handling of wake-up
  ACPI: Introduce new device wakeup flag 'prepared'
  ACPI: Introduce acpi_device_sleep_wake function
  PCI: rework pci_set_power_state function to call platform first
  PCI: Introduce platform_pci_power_manageable function
  ACPI: Introduce acpi_bus_power_manageable function
  PCI: make pci_name use dev_name
  PCI: handle pci_name() being const
  PCI: add stub for pci_set_consistent_dma_mask()
  PCI: remove unused arch pcibios_update_resource() functions
  PCI: fix pci_setup_device()'s sprinting into a const buffer
  ...

Fixed up conflicts in various files (arch/x86/kernel/setup_64.c,
arch/x86/pci/irq.c, arch/x86/pci/pci.h, drivers/acpi/sleep/main.c,
drivers/pci/pci.c, drivers/pci/pci.h, include/acpi/acpi_bus.h) from x86
and ACPI updates manually.

+ *
+ * PCI slots have first class attributes such as address, speed, width,
+ * and a &struct pci_slot is used to manage them. This interface will
+ * either return a new &struct pci_slot to the caller, or if the pci_slot
+ * already exists, its refcount will be incremented.
+ *
+ * Slots are uniquely identified by a @pci_bus, @slot_nr, @name tuple.
+ *
+ * Placeholder slots:
+ * In most cases, @pci_bus, @slot_nr will be sufficient to uniquely identify
+ * a slot. There is one notable exception - pSeries (rpaphp), where the
+ * @slot_nr cannot be determined until a device is actually inserted into
+ * the slot. In this scenario, the caller may pass -1 for @slot_nr.
+ *
+ * The following semantics are imposed when the caller passes @slot_nr ==
+ * -1. First, the check for existing %struct pci_slot is skipped, as the
+ * caller may know about several unpopulated slots on a given %struct
+ * pci_bus, and each slot would have a @slot_nr of -1.  Uniqueness for
+ * these slots is then determined by the @name parameter. We expect
+ * kobject_init_and_add() to warn us if the caller attempts to create
+ * multiple slots with the same name. The other change in semantics is
+ * user-visible, which is the 'address' parameter presented in sysfs will
+ * consist solely of a dddd:bb tuple, where dddd is the PCI domain of the
+ * %struct pci_bus and bb is the bus number. In other words, the devfn of

  * 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().
+ *
+ * All of the above callbacks, except for @complete(), return error codes.
+ * However, the error codes returned by the resume operations, @resume(),
+ * @thaw(), and @restore(), 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
