Subject[GIT PULL] ACPI and power management fixes for v3.14-rc5
From
Hi Linus,

Please pull from the git repository at

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm+acpi-3.14-rc5

to receive ACPI and power management fixes for v3.14-rc5
with top-most commit 6c09ea49ceb8a3b2b709718f6acdb1edd92ea899

Merge branches 'pm-cpufreq', 'pm-hibernate' and 'acpi-processor'

on top of commit cfbf8d4857c26a8a307fb7cd258074c9dcd8c691

Linux 3.14-rc4

These three commits fix a recent intel_pstate regression and two old
bugs that should be fixed in -stable too, one in the ACPI processor
driver and one in the firmare loader.

Specifics:

- One of the recent intel_pstate driver fixes introduced a rounding
error that on some systems causes the frequency to be stuck at the
lowest level forever. Fix from Dirk Brandewie.

- The firmware_class driver's PM notifier doesn't handle the
PM_RESTORE_PREPARE event during hibernation image restore and that
leads to a deadlock on umhelper_sem in __usermodehelper_disable().
Fix from Sebastian Capella.

- acpi_processor_set_throttling() abuses set_cpus_allowed_ptr() in a
nasty way which triggers the WARN_ON_ONCE() in wq_worker_waking_up()
among other things. Fix from Lan Tianyu.

Thanks!
