    Merge tag 'pm+acpi-4.1-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
    
    Pull power management and ACPI fixes from Rafael Wysocki:
     "Three regression fixes this time, one for a recent regression in the
      cpuidle core affecting multiple systems, one for an inadvertently
      added duplicate typedef in ACPICA that breaks compilation with GCC 4.5
      and one for an ACPI Smart Battery Subsystem driver regression
      introduced during the 3.18 cycle (stable-candidate).
    
      Specifics:
    
       - Fix for a regression in the cpuidle core introduced by one of the
         recent commits in the clockevents_notify() removal series that put
         a call to a function which had to be executed with disabled
         interrupts into a code path running with enabled interrupts (Rafael
         J Wysocki)
    
       - Fix for a build problem in ACPICA (with GCC 4.5) introduced by one
         of the recent ACPICA tools commits that added a duplicate typedef
         to one of the ACPICA's header files by mistake (Olaf Hering)
    
       - Fix for a regression in the ACPI SBS (Smart Battery Subsystem)
         driver introduced during the 3.18 development cycle causing the
         smart battery manager to be marked as not present when it should be
         marked as present (Chris Bainbridge)"
