Merge tag 'pm-for-3.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael J. Wysocki:

 - Fix for two recent regressions in the generic PM domains framework.

 - Revert of a commit that introduced a resume regression and is
   conceptually incorrect in my opinion.

 - Fix for a return value in pcc-cpufreq.c from Julia Lawall.

 - RTC wakeup signaling fix from Neil Brown.

 - Suppression of compiler warnings for CONFIG_PM_SLEEP unset in ACPI,
   platform/x86 and TPM drivers.
