Merge branches 'pm-sleep' and 'pm-cpufreq'

on top of commit 7a308bb3016f57e5be11a677d15b821536419d36

Linux 4.10-rc5

to receive power management fixes for v4.10-rc6.

These fix two regressions introduced recently, one by reverting the
problematic commit and one by fixing up the behavior in an overlooked


- Revert the recent change that caused suspend-to-idle to be used
as the default suspend method on systems where it is indicated to
be efficient by the ACPI tables, as that turned out to be premature
and introduced suspend regressions on some systems with missing
power management support in device drivers (Rafael Wysocki).

- Fix up the intel_pstate driver to take changes of the global
limits via sysfs correctly when the performance policy is used
which has been broken by a recent change in it (Srinivas Pandruvada).
