Subject: [GIT PULL] Power management updates for 2.6.37

Hi Linus,

Please pull power management updates for 2.6.37 from:

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6.git for-linus

They include:

 * Runtime PM framework updates from Alan Stern and me.  The autosuspend
   feature is now available at the core level to drivers wanting to use it.

 * Hibernate image compression from Bojan Smojver.

 * Operating Performance Points framework from Nishanth Menon.

 * Hibernate improvements and fixes.

 * sysfs attribute for checking pm_trace device matches from James Hogan.

 * Extension of the wakeup events code for collecting wakeup sources
   statistics.
