Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.15-rc1-2

to receive more ACPI and power management updates for v3.15-rc1 with
top-most commit 7b5c39389c86063e86fe8f2e0093c7197ddfa60a

Merge branch 'pm-runtime'

on top of commit 0ecfe310f4517d7505599be738158087c165be7c

Merge branch 'pm-devfreq'

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.

Thanks!
