Linus Torvalds 6453dbdda3 Power management material for v4.8-rc1
- Rework the cpufreq governor interface to make it more straightforward
    and modify the conservative governor to avoid using transition
    notifications (Rafael Wysocki).
 
  - Rework the handling of frequency tables by the cpufreq core to make
    it more efficient (Viresh Kumar).
 
  - Modify the schedutil governor to reduce the number of wakeups it
    causes to occur in cases when the CPU frequency doesn't need to be
    changed (Steve Muckle, Viresh Kumar).
 
  - Fix some minor issues and clean up code in the cpufreq core and
    governors (Rafael Wysocki, Viresh Kumar).
 
  - Add Intel Broxton support to the intel_pstate driver (Srinivas
    Pandruvada).
 
  - Fix problems related to the config TDP feature and to the validity
    of the MSR_HWP_INTERRUPT register in intel_pstate (Jan Kiszka,
    Srinivas Pandruvada).
 
  - Make intel_pstate update the cpu_frequency tracepoint even if
    the frequency doesn't change to avoid confusing powertop (Rafael
    Wysocki).
 
  - Clean up the usage of __init/__initdata in intel_pstate, mark some
    of its internal variables as __read_mostly and drop an unused
    structure element from it (Jisheng Zhang, Carsten Emde).
 
  - Clean up the usage of some duplicate MSR symbols in intel_pstate
    and turbostat (Srinivas Pandruvada).
 
  - Update/fix the powernv, s3c24xx and mvebu cpufreq drivers (Akshay
    Adiga, Viresh Kumar, Ben Dooks).
 
  - Fix a regression (introduced during the 4.5 cycle) in the
    pcc-cpufreq driver by reverting the problematic commit (Andreas
    Herrmann).
 
  - Add support for Intel Denverton to intel_idle, clean up Broxton
    support in it and make it explicitly non-modular (Jacob Pan,
    Jan Beulich, Paul Gortmaker).
 
  - Add support for Denverton and Ivy Bridge server to the Intel RAPL
    power capping driver and make it more careful about the handing
    of MSRs that may not be present (Jacob Pan, Xiaolong Wang).
 
  - Fix resume from hibernation on x86-64 by making the CPU offline
    during resume avoid using MONITOR/MWAIT in the "play dead" loop
    which may lead to an inadvertent "revival" of a "dead" CPU and
    a page fault leading to a kernel crash from it (Rafael Wysocki).
 
  - Make memory management during resume from hibernation more
    straightforward (Rafael Wysocki).
 
  - Add debug features that should help to detect problems related
    to hibernation and resume from it (Rafael Wysocki, Chen Yu).
 
  - Clean up hibernation core somewhat (Rafael Wysocki).
 
  - Prevent KASAN from instrumenting the hibernation core which leads
    to large numbers of false-positives from it (James Morse).
 
  - Prevent PM (hibernate and suspend) notifiers from being called
    during the cleanup phase if they have not been called during the
    corresponding preparation phase which is possible if one of the
    other notifiers returns an error at that time (Lianwei Wang).
 
  - Improve suspend-related debug printout in the tasks freezer and
    clean up suspend-related console handling (Roger Lu, Borislav
    Petkov).
 
  - Update the AnalyzeSuspend script in the kernel sources to
    version 4.2 (Todd Brandt).
 
  - Modify the generic power domains framework to make it handle
    system suspend/resume better (Ulf Hansson).
 
  - Make the runtime PM framework avoid resuming devices synchronously
    when user space changes the runtime PM settings for them and
    improve its error reporting (Rafael Wysocki, Linus Walleij).
 
  - Fix error paths in devfreq drivers (exynos, exynos-ppmu, exynos-bus)
    and in the core, make some devfreq code explicitly non-modular and
    change some of it into tristate (Bartlomiej Zolnierkiewicz,
    Peter Chen, Paul Gortmaker).
 
  - Add DT support to the generic PM clocks management code and make
    it export some more symbols (Jon Hunter, Paul Gortmaker).
 
  - Make the PCI PM core code slightly more robust against possible
    driver errors (Andy Shevchenko).
 
  - Make it possible to change DESTDIR and PREFIX in turbostat
    (Andy Shevchenko).

Pull power management updates from Rafael  Wysocki:
 "Again, the majority of changes go into the cpufreq subsystem, but
  there are no big features this time.  The cpufreq changes that stand
  out somewhat are the governor interface rework and improvements
  related to the handling of frequency tables.  Apart from those, there
  are fixes and new device/CPU IDs in drivers, cleanups and an
  improvement of the new schedutil governor.

  Next, there are some changes in the hibernation core, including a fix
  for a nasty problem related to the MONITOR/MWAIT usage by CPU offline
  during resume from hibernation, a few core improvements related to
  memory management during resume, a couple of additional debug features
  and cleanups.

  Finally, we have some fixes and cleanups in the devfreq subsystem,
  generic power domains framework improvements related to system
  suspend/resume, support for some new chips in intel_idle and in the
  power capping RAPL driver, a new version of the AnalyzeSuspend utility
  and some assorted fixes and cleanups.

  Specifics:

   - Rework the cpufreq governor interface to make it more
     straightforward and modify the conservative governor to avoid using
     transition notifications (Rafael Wysocki).
