Merge tag 'pm+acpi-for-3.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes from Rafael Wysocki:

 - cpuidle regression fix related to the initialization of state
   kobjects from Krzysztof Mazur.

 - cpuidle fix removing some not very useful code and making some
   user-visible problems go away at the same time.  From Daniel Lezcano.

 - ACPI build fix from Yinghai Lu.

* tag 'pm+acpi-for-3.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  cpuidle: remove the power_specified field in the driver
  ACPI / glue: Fix build with ACPI_GLUE_DEBUG set
  cpuidle: fix number of initialized/destroyed states
