Merge tag 'pm+acpi-3.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are an ACPI device power management initialization fix (-stable
  material), two commits renaming stuff in the ACPI processor driver to
  make it more suitable for ARM64 processors and a new ACPI backlight
  blacklist entry.

  Specifics:

   - Fix ACPI power management intialization for device objects
     corresponding to devices that are not present at the init time (the
     _STA control method returns 0 for them) and therefore should not be
     regarded as power manageable (Rafael J Wysocki).

   - Rename a structure field and two functions used by the ACPI
     processor driver to make them less tied to architectures that use
     APICs (both x86 and ia64) and more suitable for ARM64 processors
     (Hanjun Guo).

   - Add a disable_native_backlight quirk for Dell XPS15 L521X designed
     in an unusual way preventing native backlight from working on that
     machine (Hans de Goede)"

  ACPI / video: Add disable_native_backlight quirk for Dell XPS15 L521X
  ACPI / processor: Rename acpi_(un)map_lsapic() to acpi_(un)map_cpu()
  ACPI / processor: Convert apic_id to phys_id to make it arch agnostic
  ACPI / PM: Fix PM initialization for devices that are not present
