Linus Torvalds b528392669 ACPI and power management updates for 3.18-rc1 
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
 
  - PM core fix related to clock management (Geert Uytterhoeven).
 
  - PM core's sysfs code cleanup (Johannes Berg).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()
     and in that mode the first interrupt will abort system suspend in
     progress or wake up the system if already in suspend-to-idle (or
     equivalent) without executing any interrupt handlers.  Among other
     things that eliminates the wakeup-related motivation to use the
     IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
     need it and should not use it (Thomas Gleixner and Rafael Wysocki)

     devices can be added to PM domains automatically during enumeration

     Villemoes)

   - ARM big.LITTLE cpuidle driver updates: support for DT-based
     initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
     Kevin Hilman)

   - Rework of the test_suspend kernel command line argument and a new
     trace event for console resume (Srinivas Pandruvada, Todd E Brandt)

   - Second attempt to optimize swsusp_free() (hibernation core) to make

     update in MAINTAINERS (Heiko Stübner, Kevin Hilman)
