Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-4.4-rc3

to receive power management and ACPI fixes for v4.4-rc3 with
top-most commit f28a1b0df7adcc981e5ce5a5daf3d638dd019c0e

Merge branches 'pm-cpufreq' and 'acpi-cppc'

on top of commit 1ec218373b8ebda821aec00bb156a9c94fad9cd4

Linux 4.4-rc2

These fix one recent regression (cpufreq core), fix up two features
added recently (ACPI CPPC support, SCPI support in the arm_big_little
cpufreq driver) and fix three older bugs in the intel_pstate driver.

Specifics:

- Fix a recent regression in the cpufreq core causing it to fail
to clean up sysfs directories properly on cpufreq driver removal
(Viresh Kumar).

- Fix a build problem in the SCPI support code recently added to
the arm_big_little cpufreq driver (Punit Agrawal).

- Fix up the recently added CPPC cpufreq frontend to process the
CPU coordination information provided by the platform firmware
correctly (Ashwin Chaugule).

- Fix the intel_pstate driver to behave as intended when switched
over to the "performance" mode via sysfs if hardware-driven
P-state selection (HWP) is enabled (Alexandra Yates).

- Fix two rounding errors in the intel_pstate driver that sometimes
cause it to use lower P-states than requested (Prarit Bhargava).

Thanks!
