Linus Torvalds 3d7a6db537 Power management and ACPI fixes for v4.0-rc5
- Revert a recent PCI commit related to IRQ resources management
    that introduced a regression for drivers attempting to bind to
    devices whose previous drivers did not balance pci_enable_device()
    and pci_disable_device() as expected (Rafael J Wysocki).
 
  - Fix a deadlock in at91_rtc_interrupt() introduced by a typo in a
    recent commit related to wakeup interrupt handling (Dan Carpenter).
 
  - Allow the power capping RAPL (Running-Average Power Limit) driver
    to use different energy units for domains within one CPU package
    which is necessary to handle Intel Haswell EP processors correctly
    (Jacob Pan).
 
  - Improve the cpuidle mvebu driver's handling of Armada XP SoCs by
    updating the target residency and exit latency numbers for those
    chips (Sebastien Rannou).
 
  - Prevent the cpuidle mvebu driver from calling cpu_pm_enter() twice
    in a row before cpu_pm_exit() is called on the same CPU which
    breaks the core's assumptions regarding the usage of those
    functions (Gregory Clement).

Pull power management and ACPI fixes from Rafael Wysocki:
 "These are fixes for recent regressions (PCI/ACPI resources and at91
  RTC locking), a stable-candidate powercap RAPL driver fix and two ARM
  cpuidle fixes (one stable-candidate too).

  Specifics:

   - Revert a recent PCI commit related to IRQ resources management that
     introduced a regression for drivers attempting to bind to devices
     whose previous drivers did not balance pci_enable_device() and
     pci_disable_device() as expected (Rafael J Wysocki).

   - Fix a deadlock in at91_rtc_interrupt() introduced by a typo in a
     recent commit related to wakeup interrupt handling (Dan Carpenter).

   - Allow the power capping RAPL (Running-Average Power Limit) driver
     to use different energy units for domains within one CPU package
     which is necessary to handle Intel Haswell EP processors correctly
     (Jacob Pan).

   - Improve the cpuidle mvebu driver's handling of Armada XP SoCs by
     updating the target residency and exit latency numbers for those
     chips (Sebastien Rannou).

   - Prevent the cpuidle mvebu driver from calling cpu_pm_enter() twice
