Linus Torvalds 39ed853a24 Power management and ACPI fixes for v4.0-rc3
- Fix ACPI resources management problems introduced by the recent
    rework of the code in question (Jiang Liu) and a build issue
    introduced by those changes (Joachim Nilsson).
 
  - Fix a recent suspend-to-idle regression on systems where entering
    idle states causes local timers to stop, prevent suspend-to-idle
    from crashing in restricted configurations (no cpuidle driver,
    cpuidle disabled etc.) and clean up the idle loop somewhat while
    at it (Rafael J Wysocki).
 
  - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
 
  - Allow the ACPI backlight driver module to be loaded if ACPI is
    disabled which helps the i915 driver in those configurations
    (stable-candidate) and change the code to help debug unusual use
    cases (Chris Wilson).
 
  - Wakeup IRQ management changes in v3.18 caused some drivers on the
    at91 platform to trigger a warning from the IRQ core related to
    an unexpected combination of interrupt action handler flags.
    However, on at91 a timer IRQ is shared with some other devices
    (including system wakeup ones) and that leads to the unusual
    combination of flags in question.  To make it possible to avoid
    the warning introduce a new interrupt action handler flag (which
    can be used by drivers to indicate the special case to the core)
    and rework the problematic at91 drivers to use it and work as
    expected during system suspend/resume.  From Boris Brezillon,
    Rafael J Wysocki and Mark Rutland.
 
  - Clean up the generic power domains subsystem's debugfs interface
    (Kevin Hilman).

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes for recent regressions (ACPI resources management,
  suspend-to-idle), stable-candidate fixes (ACPI backlight), fixes
  related to the wakeup IRQ management changes made in v3.18, other
  fixes (suspend-to-idle, cpufreq ppc driver) and a couple of cleanups
  (suspend-to-idle, generic power domains, ACPI backlight).

  Specifics:

   - Fix ACPI resources management problems introduced by the recent
     rework of the code in question (Jiang Liu) and a build issue
     introduced by those changes (Joachim Nilsson).

   - Fix a recent suspend-to-idle regression on systems where entering
     idle states causes local timers to stop, prevent suspend-to-idle
     from crashing in restricted configurations (no cpuidle driver,
     cpuidle disabled etc.) and clean up the idle loop somewhat while at
     it (Rafael J Wysocki).

   - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).

   - Allow the ACPI backlight driver module to be loaded if ACPI is
     disabled which helps the i915 driver in those configurations
     (stable-candidate) and change the code to help debug unusual use
     cases (Chris Wilson).
