Subject: [GIT PULL] More power management updates for v4.20-rc1
Date: Tue, 30 Oct 2018 09:28:01 +0100	[thread overview]
Message-ID: <CAJZ5v0g7iRUA2=fi3+rkJcsx38YTE6fx26bnnpjeMHwv_CSMVw@mail.gmail.com> (raw)

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.20-rc1-2

with top-most commit c4ac6889930d027ffa5cf77e0c202e7e97a4be06

 Merge branches 'pm-cpuidle' and 'pm-cpufreq'

on top of commit bd6bf7c10484f026505814b690104cdef27ed460

 Merge tag 'pci-v4.20-changes' of
git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

to receive additional power management updates for 4.20-rc1.

These remove a questionable heuristic from the menu cpuidle governor,
fix a recent build regression in the intel_pstate driver, clean up
ARM big-Little support in cpufreq and fix up hung task watchdog's
interaction with system-wide power management transitions.

Specifics:

 - Fix build regression in the intel_pstate driver that doesn't
   build without CONFIG_ACPI after recent changes (Dominik Brodowski).

 - One of the heuristics in the menu cpuidle governor is based on a
   function returning 0 most of the time, so drop it and clean up
   the scheduler code related to it (Daniel Lezcano).

 - Prevent the arm_big_little cpufreq driver from being used on ARM64
   which is not suitable for it and drop the arm_big_little_dt driver
   that is not used any more (Sudeep Holla).

 - Prevent the hung task watchdog from triggering during resume from
   system-wide sleep states by disabling it before freezing tasks and
   enabling it again after they have been thawed (Vitaly Kuznetsov).

There is a merge conflict between the menu governor changes included
here and the (already merged) material from Andrew, but it should be
straightforward to resolve [1].

Thanks!
