Subject: [GIT PULL] More power management updates for v4.18-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.18-rc1-2

with top-most commit 6a900f884e3e864d13501e63357990bc472f940c

 Merge branches 'pm-domains' and 'pm-tools'

on top of commit 3c89adb0d11117f64d5b501730be7fb2bf53a479

 Merge tag 'pm-4.18-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive additional power management updates for 4.18-rc1.

These revert a recent PM core change that introduced a regression,
fix build when the recently added Kryo cpufreq driver is selected,
add support for devices attached to multiple power domains to the
generic power domains (genpd) framework, add support for iowait
boosting on systens with hardware-managed P-states (HWP) enabled
to the intel_pstate driver, modify the behavior of the wakeup_count
device attribute in sysfs, fix a few issues and clean up some
ugliness, mostly in cpufreq (core and drivers) and in the cpupower
utility.

Specifics:

 - Revert a recent PM core change that attempted to fix an issue
   related to device links, but introduced a regression (Rafael
   Wysocki).

 - Fix build when the recently added cpufreq driver for Kryo
   processors is selected by making it possible to build that
   driver as a module (Arnd Bergmann).

 - Fix the long idle detection mechanism in the out-of-band
   (ondemand and conservative) cpufreq governors (Chen Yu).

 - Add support for devices in multiple power domains to the
   generic power domains (genpd) framework (Ulf Hansson).

 - Add support for iowait boosting on systems with hardware-managed
   P-states (HWP) enabled to the intel_pstate driver and make it use
   that feature on systems with Skylake Xeon processors as it is
   reported to improve performance significantly on those systems
   (Srinivas Pandruvada).

 - Fix and update the acpi_cpufreq, ti-cpufreq and imx6q cpufreq
   drivers (Colin Ian King, Suman Anna, Sébastien Szymanski).

 - Change the behavior of the wakeup_count device attribute in
   sysfs to expose the number of events when the device might have
   aborted system suspend in progress (Ravi Chandra Sadineni).

 - Fix two minor issues in the cpupower utility (Abhishek Goel,
   Colin Ian King).

Thanks!
