Linus Torvalds 400f3f255d More power management and ACPI updates for v4.4-rc2
- Revert three recent intel_pstate driver commits one of which
    introduced a regression and the remaining two depend on the
    problematic one (Rafael Wysocki).
 
  - Fix breakage related to the recently introduced ACPI _CCA object
    support in the PCI DMA setup code (Suravee Suthikulpanit).
 
  - Fix up the recently introduced ACPI CPPC support to only
    use the hardware-reduced version of the PCCT structure as
    the only architecture to support it (ARM64) will only use
    hardware-reduced ACPI anyway (Ashwin Chaugule).
 
  - Fix a cpufreq mediatek driver build problem (Arnd Bergmann).
 
  - Fix the SMBus transaction handling implementation in the ACPI
    core to avoid re-entrant calls to wait_event_timeout() which
    makes intermittent boot stalls related to the Smart Battery
    Subsystem initialization go away and revert a workaround of
    another problem with the same underlying root cause (Chris
    Bainbridge).
 
  - Fix the generic wakeup interrupts framework to avoid using
    invalid IRQ numbers (Dmitry Torokhov).
 
  - Remove a redundant check from the ACPI EC driver (Markus Elfring).
 
  - Modify the intel_pstate driver so it can support more Atom flavors
    than just one (Baytrail) and add support for Atom Airmont cores
    (which require new freqnency tables) to it (Philippe Longepe).
 
  - Clean up MSR-related symbols in turbostat (Len Brown).

Merge tag 'pm+acpi-4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes and cleanups (ACPI core, PM core, cpufreq, ACPI
  EC driver, device properties) including three reverts of recent
  intel_pstate driver commits due to a regression introduced by one of
  them plus support for Atom Airmont cores in intel_pstate (which really
  boils down to adding new frequency tables for Airmont) and additional
  turbostat updates.

  Specifics:

   - Revert three recent intel_pstate driver commits one of which
     introduced a regression and the remaining two depend on the
     problematic one (Rafael Wysocki).

   - Fix breakage related to the recently introduced ACPI _CCA object
     support in the PCI DMA setup code (Suravee Suthikulpanit).

   - Fix up the recently introduced ACPI CPPC support to only use the
     hardware-reduced version of the PCCT structure as the only
     architecture to support it (ARM64) will only use hardware-reduced
     ACPI anyway (Ashwin Chaugule).

   - Fix a cpufreq mediatek driver build problem (Arnd Bergmann).

   - Fix the SMBus transaction handling implementation in the ACPI core
     to avoid re-entrant calls to wait_event_timeout() which makes
     intermittent boot stalls related to the Smart Battery Subsystem
     initialization go away and revert a workaround of another problem
     with the same underlying root cause (Chris Bainbridge).

   - Fix the generic wakeup interrupts framework to avoid using invalid
     IRQ numbers (Dmitry Torokhov).

   - Remove a redundant check from the ACPI EC driver (Markus Elfring).

   - Modify the intel_pstate driver so it can support more Atom flavors
     than just one (Baytrail) and add support for Atom Airmont cores
     (which require new freqnency tables) to it (Philippe Longepe).

   - Clean up MSR-related symbols in turbostat (Len Brown)"
