Merge tag 'acpica-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPICA updates from Rafael Wysocki:
 "This updates the kernel's ACPICA code to upstream revision 20150410
  and adds a fix for a GPE handling regression introduced during the
  3.19 cycle on top of that.

  Included are two stable-candidate bug fixes (one of them fixing a 3.16
  regression), multiple other fixes and a bunch of cleanups.

  Specifics:

   - Fix for a GPE handling regression on Dell Latitude D600 that caused
     GPE signaling to stop working on that machine, which appears to be
     due to a hardware glitch, but it used to work and it can be made
     work again in a relativly straightforward way (Rafael J Wysocki).

   - Fix for a mutex unlock regression related to the handling of ACPI
     tables introduced during the 3.16 development cycle (Octavian
     Purdila).

   - _REV modification to always return 2 which has been done by all
     versions of Windows since NT and the firmware people started to use
     it to distinguish between OSes in their AML and do some silly and
     wrong things on that basis (Bob Moore).

   - Fixes and cleanups related to the acpi_physicall_address data type
     including one stable-candidate fix for an issue occasionally
     occuring on 64-bit machines running 32-bit kernels where using
     offsets provided by the firmware may lead to address overflows (Lv
     Zheng).

   - External() opcode support infrastructure needed for recompiling
     disassembled ACPI tables in some cases including interpreter
     modification to ignore that opcode (Bob Moore).

   - Support for the "Windows 2015" string in _OSI (Bob Moore).

   - GPE debug interface change to return values read from hardware
     registers (Lv Zheng).

   - Removal of the __DATE__ macro usage in tools (Rasmus Villemoes).

   - Assorted minor fixes and cleanups (Lv Zheng, Rickard Strandqvist,
     Bob Moore)"
