Subject: [GIT PULL] Power management and ACPI fixes for v4.5-rc2

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-4.5-rc2

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
cleanup.

Specifics:

 - 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).

Thanks!
