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!
