Pull more power management updates from Rafael Wysocki:
"Additional power management updates.
These fix a corner-case suspend-to-idle wakeup issue on systems where
the ACPI SCI is shared with another wakeup source, add a kernel
command line option to set pm_debug_messages via the kernel command
line, add a document desctibing system-wide suspend and resume code
flows, modify cpufreq Kconfig to choose schedutil as the preferred
governor by default in a couple of cases and do some assorted
cleanups.
Specifics:
- Fix corner-case suspend-to-idle wakeup issue on systems where the
ACPI SCI is shared with another wakeup source (Hans de Goede).
- Add document describing system-wide suspend and resume code flows
to the admin guide (Rafael Wysocki).
- Add kernel command line option to set pm_debug_messages (Chen Yu).
- Choose schedutil as the preferred scaling governor by default on
ARM big.LITTLE systems and on x86 systems using the intel_pstate
driver in the passive mode (Linus Walleij, Rafael Wysocki).
- Drop racy and redundant checks from the PM core's device_prepare()
routine (Rafael Wysocki).
- Make resume from hibernation take the hibernation_restore() return
value into account (Dexuan Cui)"
