[GIT PULL] Power management fixes for 2.6.37

[Rafael J. Wysocki]

Hi Linus,

Please pull power management fixes for 2.6.37 from:

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6.git pm-fixes

They include:

* Restoration of the old hibernate swap signature (I wanted to change it to
  avoid some potential problems, but it turned out that user space used the
  old signature and obviously didn't understand the new one).

* Fix for an ancient bug in the hibernate user interface from Takashi
  (the bug has been there forever, but we didn't have any code where it really
  mattered until very recently).

* Fix for a bug in pm_runtime_suspended() that prevents some devices from being
  suspended and resumed when they should, so it is potentially deadly.
