[GIT PULL] Power management updates for 2.6.39

[Rafael J. Wysocki]

Hi Linus,

Please pull power management updates for 2.6.39 from:

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

They include:

* Wakeup sources framework fixes.

* PM core modification preventing sysfs files related to wakeup from being
  created for devices that can't wake up the system.

* Reduction of the number of power management Kconfig options.

* Runtime PM framework modification allowing pm_runtime_suspend() to succeed
  during system suspend.

* Removal of pm_flags.

* Support for device power domains in the core PM code.

* PM core and runtime PM framework modification making them treat subsystems
  in a consistent way.

* Introduction of struct syscore_ops for implementing core subsystems'
  suspend/resume and shutdown operations without using sysdevs.

* Various PM-related fixes.
