 ACPI and power management updates for 3.16-rc1
 
  - ACPICA update to upstream version 20140424.  That includes a
    number of fixes and improvements related to things like GPE
    handling, table loading, headers, memory mapping and unmapping,
    DSDT/SSDT overriding, and the Unload() operator.  The acpidump
    utility from upstream ACPICA is included too.  From Bob Moore,
    Lv Zheng, David Box, David Binderman, and Colin Ian King.
 
  - Fixes and cleanups related to ACPI video and backlight interfaces
    from Hans de Goede.  That includes blacklist entries for some new
    machines and using native backlight by default.
 
  - ACPI device enumeration changes to create platform devices
    rather than PNP devices for ACPI device objects with _HID by
    default.  PNP devices will still be created for the ACPI device
    object with device IDs corresponding to real PNP devices, so
    that change should not break things left and right, and we're
    expecting to see more and more ACPI-enumerated platform devices
    in the future.  From Zhang Rui and Rafael J Wysocki.
 
  - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing
    it to handle system suspend/resume on Asus T100 correctly.
    From Heikki Krogerus and Rafael J Wysocki.
 
  - PM core update introducing a mechanism to allow runtime-suspended
    devices to stay suspended over system suspend/resume transitions
    if certain additional conditions related to coordination within
    device hierarchy are met.  Related PM documentation update and
    ACPI PM domain support for the new feature.  From Rafael J Wysocki.
 
  - Fixes and improvements related to the "freeze" sleep state. They
    affect several places including cpuidle, PM core, ACPI core, and
    the ACPI battery driver.  From Rafael J Wysocki and Zhang Rui.
 
  - Miscellaneous fixes and updates of the ACPI core from Aaron Lu,
    Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki.
 
  - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor
    Aggregator Device) drivers from Baoquan He, Manuel Schölling,
    Tony Camuso, and Toshi Kani.
 
  - System suspend/resume optimization in the ACPI battery driver from
    Lan Tianyu.
 
  - OPP (Operating Performance Points) subsystem updates from
    Chander Kashyap, Mark Brown, and Nishanth Menon.
 
  - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat,
    Stratos Karafotis, and Viresh Kumar.
 
  - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q,
    s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris,
    Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and
    Viresh Kumar.
 
  - intel_pstate driver fixes and cleanups from Dirk Brandewie,
    Doug Smythies, and Stratos Karafotis.
 
  - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown.
 
  - Fix for the cpuidle menu governor from Chander Kashyap.
 
  - New ARM clps711x cpuidle driver from Alexander Shiyan.
 
  - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter,
    Fabian Frederick, Pali Rohár, and Sebastian Capella.
 
  - Intel RAPL (Running Average Power Limit) driver updates from
    Jacob Pan.
 
  - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick.
 
  - devfreq core updates from Chanwoo Choi and Paul Bolle.
 
  - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and
    Bartlomiej Zolnierkiewicz.
 
  - turbostat tool fix from Jean Delvare.
 
  - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra
    and Thomas Renninger.
 
  - New ACPI ec_access.c tool for poking at the EC in a safe way

Pull ACPI and power management updates from Rafael Wysocki:
 "ACPICA is the leader this time (63 commits), followed by cpufreq (28
  commits), devfreq (15 commits), system suspend/hibernation (12
  commits), ACPI video and ACPI device enumeration (10 commits each).

  We have no major new features this time, but there are a few
  significant changes of how things work.  The most visible one will
  probably be that we are now going to create platform devices rather
  than PNP devices by default for ACPI device objects with _HID.  That
  was long overdue and will be really necessary to be able to use the
  same drivers for the same hardware blocks on ACPI and DT-based systems
  going forward.  We're not expecting fallout from this one (as usual),
  but it's something to watch nevertheless.

  The second change having a chance to be visible is that ACPI video
  will now default to using native backlight rather than the ACPI
  backlight interface which should generally help systems with broken
  Win8 BIOSes.  We're hoping that all problems with the native backlight
  handling that we had previously have been addressed and we are in a
  good enough shape to flip the default, but this change should be easy
  enough to revert if need be.

  In addition to that, the system suspend core has a new mechanism to
  allow runtime-suspended devices to stay suspended throughout system
  suspend/resume transitions if some extra conditions are met
  (generally, they are related to coordination within device hierarchy).
  However, enabling this feature requires cooperation from the bus type
  layer and for now it has only been implemented for the ACPI PM domain
  (used by ACPI-enumerated platform devices mostly today).

  Also, the acpidump utility that was previously shipped as a separate
  tool will now be provided by the upstream ACPICA along with the rest
  of ACPICA code, which will allow it to be more up to date and better
  supported, and we have one new cpuidle driver (ARM clps711x).

  The rest is improvements related to certain specific use cases,
  cleanups and fixes all over the place.

  Specifics:

   - ACPICA update to upstream version 20140424.  That includes a number
     of fixes and improvements related to things like GPE handling,
     table loading, headers, memory mapping and unmapping, DSDT/SSDT
     overriding, and the Unload() operator.  The acpidump utility from
     upstream ACPICA is included too.  From Bob Moore, Lv Zheng, David
     Box, David Binderman, and Colin Ian King.

   - Fixes and cleanups related to ACPI video and backlight interfaces
     from Hans de Goede.  That includes blacklist entries for some new
     machines and using native backlight by default.

   - ACPI device enumeration changes to create platform devices rather
     than PNP devices for ACPI device objects with _HID by default.  PNP
     devices will still be created for the ACPI device object with
     device IDs corresponding to real PNP devices, so that change should
     not break things left and right, and we're expecting to see more
     and more ACPI-enumerated platform devices in the future.  From
     Zhang Rui and Rafael J Wysocki.

   - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
     to handle system suspend/resume on Asus T100 correctly.  From
     Heikki Krogerus and Rafael J Wysocki.

   - PM core update introducing a mechanism to allow runtime-suspended
     devices to stay suspended over system suspend/resume transitions if
     certain additional conditions related to coordination within device
     hierarchy are met.  Related PM documentation update and ACPI PM
     domain support for the new feature.  From Rafael J Wysocki.

     Kashyap, Mark Brown, and Nishanth Menon.

     Stratos Karafotis, and Viresh Kumar.
