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" * 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.
