[GIT PULL] Power management and ACPI fixes for v4.6-rc7

[Rafael J. Wysocki]

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-4.6-rc7

to receive power management and ACPI fixes for v4.6-rc7 with top-most
commit 5f2f88e330e7ee2d2d7c5e0984b86108b00ac800

 Merge branches 'pm-opp-fixes', 'pm-cpufreq-fixes' and 'pm-cpuidle-fixes'

on top of commit 04974df8049fc4240d22759a91e035082ccd18b4

 Linux 4.6-rc6

Fixes for problems introduced or discovered recently (intel_pstate,
sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
generic device properties framework) and one fix for a hotplug-related
deadlock in ACPICA that's been there forever, but is nasty enough.

Specifics:

 - Fix for a recent regression in the intel_pstate driver causing
   it to fail to restore the HWP (HW-managed P-states) configuration
   of the boot CPU after suspend-to-RAM (Rafael Wysocki).

 - Fix for two recent regressions in the intel_pstate driver, one
   that can trigger a divide by zero if the driver is accessed via
   sysfs before it manages to take the first sample and one causing
   it to fail to update a structure field used in a trace point, so
   the information coming from it is less useful (Rafael Wysocki).

 - Fix for a problem in the sti-cpufreq driver introduced during
   the 4.5 cycle that causes it to break CPU PM in multi-platform
   kernels by registering cpufreq-dt (which subsequently doesn't
   work) unconditionally and preventing the driver that would
   actually work from registering (Sudeep Holla).

 - Stable-candidate fix for an ARM64 cpuidle issue causing idle
   state usage counters to be incorrectly updated for idle states
   that were not entered due to errors (James Morse).

 - Fix for a recently introduced issue in the OPP (Operating
   Performance Points) framework causing it to print bogus error
   messages for missing optional regulators (Viresh Kumar).

 - Fix for a recently introduced issue in the generic device
   properties framework that may cause it to attempt to dereferece
   and invalid pointer in some cases (Heikki Krogerus).

 - Fix for a deadlock in the ACPICA core that may be triggered
   by device (eg. Thunderbolt) hotplug (Prarit Bhargava).

Thanks!
