Pull ACPI and power management fixes from Rafael Wysocki:
 "These include a fix for a recent ACPI hotplug regression, four
  concurrency related fixes and one PCI device removal fix for
  ACPI-based PCI hotplug (ACPIPHP), intel_pstate fix that should go into
  stable, three simple ACPI cleanups and a new entry for the ACPI video
  blacklist.

  Specifics:

   - Fix for a recent ACPI hotplug regression causing a NULL pointer
     dereference to occur while handling ACPI eject notifications for
     already ejected devices.  From Toshi Kani.

   - Four concurrency-related fixes for ACPIPHP.  Two of them add
     missing locking and the other two fix race conditions related to
     reference counting.

   - ACPIPHP fix to avoid NULL pointer dereferences during device
     removal involving Virtual Funcions.

   - intel_pstate fix to make it compute the percentage of time the CPU
     is busy properly.  From Dirk Brandewie.

   - Removal of two unnecessary NULL pointer checks in ACPI code and a
     fix for sscanf() format string from Dan Carpenter and Luis G.F.

   - New ACPI video blacklist entry for HP EliteBook Revolve 810 from
     Mika Westerberg"
