[GIT PULL] PM updates for 2.6.32

[GIT PULL] PM updates for 2.6.32

[Rafael J. Wysocki]

Hi Linus,

Please pull power management updates for 2.6.32 from:

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

They include:

* The run-time PM framework, most basic bits to extend in future.
  It's functional, so subsystems can start using it right now,
  documentation is included (the upcoming sh-2.6 update contains some
  code depending on this already).

* Platform bus type support for run-time PM from Magnus Damm.

* Removal of the platform bus type's suspend_late()/resume_early()
  callbacks and converting the drivers that used them to struct
  dev_pm_ops.

* Rework of the hibernation freeing of memory (we're now almost
  ready to drop shrink_all_memory() altogether).

* A few bug fixes
