[GIT PULL] Power management updates for 3.1

[Rafael J. Wysocki]

Hi Linus,

Please pull power management updates for 3.1 from:

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

They include:

* Introduction of core PM code to support power domains and related
  modifications of the ARM shmobile platform which is its first user (the
  Samsung exynos4 platform is going to use it too).

* Modifications of the runtime PM framework clarifying its interactions with
  the core system suspend/resume and hibernate code and related changes of the
  ARM OMAP platform.

* Various PM fixes and extensions.
