Revision 751a03c3728ed393287374078b98c3094a0b3bd2 authored by Linus Torvalds on 02 March 2014, 03:28:38 UTC, committed by Linus Torvalds on 02 March 2014, 03:28:38 UTC
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"
