Power management updates for 3.5
Hi Linus,
Please pull power management updates for 3.5 since commit d48b97b403d23f6df0b990cee652bdf9a52337a3:
Linux 3.4-rc6
with top-most commit 8714c8d74d313c3ba27bf9c2aaacb1ad71c644f8
epoll: Fix user space breakage related to EPOLLWAKEUP
from the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-for-3.5
Included are:
* 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.
Thanks!
