Subject: [GIT PULL] Power management updates for v4.20-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.20-rc1

with top-most commit cc19b05e3883efbbfd525747a86d0567b12c4d12

 Merge branches 'pm-devfreq' and 'pm-tools'

on top of commit 35a7f35ad1b150ddf59a41dcac7b2fa32982be0e

 Linux 4.19-rc8

to receive power management updates for 4.20-rc1.

These make hibernation on 32-bit x86 systems work in all of the
cases in which it works on 64-bit x86 ones, update the menu
cpuidle governor and the "polling" state to make them more
efficient, add more hardware support to cpufreq drivers and fix
issues with some of them, fix a bug in the conservative cpufreq
governor, fix the operating performance points (OPP) framework
and make it more stable, update the devfreq subsystem to take
changes in the APIs used by into account and clean up some
things all over.

Specifics:

 - Backport hibernation bug fixes from x86-64 to x86-32 and
   consolidate hibernation handling on x86 to allow 32-bit
   systems to work in all of the cases in which 64-bit ones
   work (Zhimin Gu, Chen Yu).

 - Fix hibernation documentation (Vladimir D. Seleznev).

 - Update the menu cpuidle governor to fix a couple of issues
   with it, make it more efficient in some cases and clean it
   up (Rafael Wysocki).

 - Rework the cpuidle polling state implementation to make it
   more efficient (Rafael Wysocki).

 - Clean up the cpuidle core somewhat (Fieah Lim).

 - Fix the cpufreq conservative governor to take policy limits
   into account properly in some cases (Rafael Wysocki).

 - Add support for retrieving guaranteed performance information
   to the ACPI CPPC library and make the intel_pstate driver use
   it to expose the CPU base frequency via sysfs on systems with
   the hardware-managed P-states (HWP) feature enabled (Srinivas
   Pandruvada).

 - Fix clang warning in the CPPC cpufreq driver (Nathan Chancellor).

 - Get rid of device_node.name printing from cpufreq (Rob Herring).

 - Remove unnecessary unlikely() from the cpufreq core (Igor Stoppa).

 - Add support for the r8a7744 SoC to the cpufreq-dt driver (Biju Das).

 - Update the dt-platdev cpufreq driver to allow RK3399 to have
   separate tunables per cluster (Dmitry Torokhov).

 - Fix the dma_alloc_coherent() usage in the tegra186 cpufreq driver
   (Christoph Hellwig).

 - Make the imx6q cpufreq driver read OCOTP through nvmem for
   imx6ul/imx6ull (Anson Huang).

 - Fix several bugs in the operating performance points (OPP)
   framework and make it more stable (Viresh Kumar, Dave Gerlach).

 - Update the devfreq subsystem to take changes in the APIs used
   by into account, fix some issues with it and make it stop
   print device_node.name directly (Bjorn Andersson, Enric Balletbo
   i Serra, Matthias Kaehlcke, Rob Herring, Vincent Donnefort, zhong
   jiang).

 - Prepare the generic power domains (genpd) framework for dealing
   with domains containing CPUs (Ulf Hansson).

 - Prevent sysfs attributes representing low-power S0 residency
   counters from being exposed if low-power S0 support is not
   indicated in ACPI FADT (Rajneesh Bhardwaj).

 - Get rid of custom CPU features macros for Intel CPUs from the
   intel_idle and RAPL drivers (Andy Shevchenko).

 - Update the tasks freezer to list tasks that refused to freeze
   and caused a system transition to a sleep state to be aborted
   (Todd Brandt).

 - Update the pm-graph set of tools to v5.2 (Todd Brandt).

 - Fix some issues in the cpupower utility (Anders Roxell, Prarit
   Bhargava).

Thanks!
