[GIT PULL] PM updates for 2.6.34

[GIT PULL] PM updates for 2.6.34

[Rafael J. Wysocki]

Hi Linus,

Please pull power management updates for 2.6.34 from:

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

They include:

* Hibernate regression fix (quite urgent).

* Introduction of a sysfs switch for controlling runtime PM of devices.

* sysfs device power attributes documentation update.

* Asynchronous suspend and resume patchset.  Reworked and hopefully not so
  controversial any more, speeds up suspend and, more importantly, resume
  quite significantly in general.

* Hibernate cleanups from Jiri Slaby and Frans Pop.
