Hi Linus,

Please pull from

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

to receive the second batch of power management and ACPI updates for
v4.5-rc2 with top-most commit ad1ac94767aa9d74c6533e33e768a14d2715162f

Merge branches 'pm-cpuidle', 'pm-cpufreq', 'pm-domains' and 'pm-sleep'

on top of commit 92e963f50fc74041b5e9e744c330dca48e04f08d

Linux 4.5-rc1

These are: cpuidle fixes (including one fix for a recent regression),
cpufreq fixes (including fixes for two issues introduced during the
4.2 cycle), generic power domains framework fixes (two locking
fixes and one cleanup), one locking fix in the ACPI-based PCI
hotplug framework (ACPIPHP), removal of one ACPI backlight
blacklist entry that isn't necessary any more and a PM Kconfig


- Fix a recent cpuidle core regression that broke suspend-to-idle
on all systems where cpuidle drivers don't provide ->enter_freeze
callbacks for any states (Sudeep Holla).

- Drop an unnecessary symbol definition from the cpuidle core code
handling coupled CPU cores (Anders Roxell).

- Fix a race condition related to governor initialization and removal
in the cpufreq core (Viresh Kumar).

- Clean up the cpufreq core to use list_is_last() for checking if
the given policy object is the last element of a list instead of
open coding that in a clumsy way (Gautham R Shenoy).

- Fix compiler warnings in the pxa2xx and cpufreq-dt cpufreq drivers
(Arnd Bergmann).

- Fix two locking issues and clean up a comment in the generic power
domains framework (Ulf Hansson, Marek Szyprowski, Moritz Fischer).

- Fix the error code path of one function in the ACPI-based PCI
hotplug framework (ACPIPHP) that forgets to release a lock
acquired previously (Insu Yun).

- Drop the ACPI backlight blacklist entry for Dell Inspiron 5737
that is not necessary any more (Hans de Goede).

- Clean up the top-level PM Kconfig to stop requiring APM emulation
to depend on PM which in fact isn't necessary (Arnd Bergmann).



Anders Roxell (1):
cpuidle: coupled: remove unused define cpuidle_coupled_lock

Arnd Bergmann (3):
PM: APM_EMULATION does not depend on PM
cpufreq: pxa2xx: fix pxa_cpufreq_change_voltage prototype
cpufreq: cpufreq-dt: avoid uninitialized variable warnings:
