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. * tag 'pm-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (25 commits) epoll: Fix user space breakage related to EPOLLWAKEUP PM / Domains: Make it possible to add devices to inactive domains PM / Hibernate: Use get_gendisk to verify partition if resume_file is integer format PM / Domains: Fix computation of maximum domain off time PM / Domains: Fix link checking when add subdomain PM / Sleep: User space wakeup sources garbage collector Kconfig option PM / Sleep: Make the limit of user space wakeup sources configurable PM / Documentation: suspend-and-cpuhotplug.txt: Fix typo PM / Domains: Cache device stop and domain power off governor results, v3 PM / Domains: Make device removal more straightforward PM / Sleep: Fix a mistake in a conditional in autosleep_store() epoll: Add a flag, EPOLLWAKEUP, to prevent suspend while epoll events are ready PM / QoS: Create device constraints objects on notifier registration PM / Runtime: Remove device fields related to suspend time, v2 PM / Domains: Rework default domain power off governor function, v2 PM / Domains: Rework default device stop governor function, v2 PM / Sleep: Add user space interface for manipulating wakeup sources, v3 PM / Sleep: Add "prevent autosleep time" statistics to wakeup sources PM / Sleep: Implement opportunistic sleep, v2 PM / Sleep: Add wakeup_source_activate and wakeup_source_deactivate tracepoints ...
