Merge tag 'pm+acpi-3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management fixes from Rafael Wysocki:
"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"
* tag 'pm+acpi-3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI / processor: Rework processor throttling with work_on_cpu()
PM / hibernate: Fix restore hang in freeze_processes()
intel_pstate: Change busy calculation to use fixed point math.
