Subject: [GIT PULL] Power management updates for 3.3
Hi Linus,
Please pull power management updates (on top of commit
4962516b2309d76964f9df0d33e74f43b624a42d) for 3.3 from:
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-for-linus
with top-most commit c233523b3d392e530033a7587d7970dc62a02361
(Merge branch 'pm-sleep' into pm-for-linus).
They include:
* Freezer updates from Tejun.
* Suspend and hiberante fixes and cleanups from Srivatsa S. Bhat.
* Introduction of PM QoS into generic PM domains.
* Rework of the PM core making it execute driver callbacks directly if the corresponding
subsystem ones are not present.
* One more ACPI sleep DMI blacklist entry.
* Changes to make the freezer play better with NFS and sunrpc from Jeff Layton.
* devfreq updates.
* Assorted PM fixes.
Thanks!
