Merge tag 'pm-3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
- cpufreq regression fix from Bjørn Mork restoring the pre-3.12
behavior of the framework during system suspend/hibernation to avoid
garbage sysfs files from being left behind in case of a suspend error
- PNP regression fix to restore the correct states of devices after
resume from hibernation broken in 3.12. From Dmitry Torokhov.
- cpuidle fix to prevent cpuidle device unregistration from crashing
due to a NULL pointer dereference if cpuidle has been disabled from
the kernel command line. From Konrad Rzeszutek Wilk.
- intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
processors from Arne Bockholdt.
- Power capping framework fix to make the energy_uj sysfs attribute
work in accordance with the documentation. From Srinivas Pandruvada.
- epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
been compiled with CONFIG_PM_SLEEP unset (in which case that flag
should not have any effect). From Amit Pundir.
- cpufreq fix to prevent governor sysfs files from being lost over
system suspend/resume in some (arguably unusual) situations. From
Viresh Kumar.
