Merge tag 'pm+acpi-3.15-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI and power management updates from Rafael Wysocki:
"These are commits that were not quite ready when I sent the original
pull request for 3.15-rc1 several days ago, but they have spent some
time in linux-next since then and appear to be good to go. All of
them are fixes and cleanups.
Specifics:
- Remaining changes from upstream ACPICA release 20140214 that
introduce code to automatically serialize the execution of methods
creating any named objects which really cannot be executed in
parallel with each other anyway (previously ACPICA attempted to
address that by aborting methods upon conflict detection, but that
wasn't reliable enough and led to other issues). From Bob Moore
and Lv Zheng.
- intel_pstate fix to use del_timer_sync() instead of del_timer() in
the exit path before freeing the timer structure from Dirk
Brandewie (original patch from Thomas Gleixner).
- cpufreq fix related to system resume from Viresh Kumar.
- Serialization of frequency transitions in cpufreq that involve
PRECHANGE and POSTCHANGE notifications to avoid ordering issues
resulting from race conditions. From Srivatsa S Bhat and Viresh
Kumar.
- Revert of an ACPI processor driver change that was based on a
specific interpretation of the ACPI spec which may not be correct
(the relevant part of the spec appears to be incomplete). From
Hanjun Guo.
- Runtime PM core cleanups and documentation updates from Geert
Uytterhoeven.
- PNP core cleanup from Michael Opdenacker"
