Merge tag 'pm-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
- Implementation of opportunistic suspend (autosleep) and user space
interface for manipulating wakeup sources.
- Hibernate updates from Bojan Smojver and Minho Ban.
- Updates of the runtime PM core and generic PM domains framework
related to PM QoS.
- Assorted fixes.
