Merge tag 'pm+acpi-3.9-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes from Rafael J Wysocki:

 - Two fixes for the new intel_pstate driver from Dirk Brandewie.

 - Fix for incorrect usage of the .find_bridge() callback from struct
   acpi_bus_type in the USB core and subsequent removal of that callback
   from Rafael J Wysocki.

 - ACPI processor driver cleanups from Chen Gang and Syam Sidhardhan.

 - ACPI initialization and error messages fix from Joe Perches.

 - Operating Performance Points documentation improvement from Nishanth
   Menon.

 - Fixes for memory leaks and potential concurrency issues and sysfs
  attributes leaks during device removal in the core device PM QoS code
  from Rafael J Wysocki.

 - Calxeda Highbank cpufreq driver simplification from Emilio López.

 - cpufreq comment cleanup from Namhyung Kim.

 - Fix for a section mismatch in Calxeda Highbank interprocessor
   communication code from Mark Langsdorf (this is not a PM fix strictly
   speaking, but the code in question went in through the PM tree).
