[GIT PULL] More power management updates for 3.2

[GIT PULL] More power management updates for 3.2

[Rafael J. Wysocki]

Hi Linus,

Please pull more power management updates (on top of commit
1583171492eb514e267c7b51e96846b38de0f544) for 3.2 from:

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

with top-most commit d6cc76856d353a3a9c43bead33210b9216dce332
(PM / Freezer: Revert 27920651fe "PM / Freezer: Make fake_signal_wake_up() wake
TASK_KILLABLE tasks too").

All of them are either bug fixes or simple cleanups that didn't make it to my
previous pull request.

They include:

* New entry for the ACPI suspend blacklist from Dave Jones.

* Fixes and cleanups related to the interactions between suspend/hibernation
  and CPU hotplug from Srivatsa Bhat.

* Runtime PM core fix for accounting_timestamp computations (some results
  were wrong due to using int instead of unsigned long) from Venu Byravarasu.

* OPP build fix from Tony Lindgren.

* PM QoS cleanup from Guennadi Liakhovetski.

* Autosuspend fixes from Alan Stern.

* Freezer fixes from Tejun and Oleg Nesterov.

[No patches from me this time, how weird.]

Thanks!
