Pull ACPI and power management updates from Rafael Wysocki:

 - Introduction of device PM QoS flags.

 - ACPI device power management update allowing subsystems other than
   PCI to use it more easily.

 - ACPI device enumeration rework allowing additional kinds of devices
   to be enumerated via ACPI.  From Mika Westerberg, Adrian Hunter,
   Mathias Nyman, Andy Shevchenko, and Rafael J. Wysocki.

 - ACPICA update to version 20121018 from Bob Moore and Lv Zheng.

 - ACPI memory hotplug update from Wen Congyang and Yasuaki Ishimatsu.

 - Introduction of acpi_handle_<level>() messaging macros and ACPI-based
   CPU hot-remove support from Toshi Kani.

 - ACPI EC updates from Feng Tang.

 - cpufreq updates from Viresh Kumar, Fabio Baltieri and others.

 - cpuidle changes to quickly notice governor prediction failure from
   Youquan Song.

 - Support for using multiple cpuidle drivers at the same time and
   cpuidle cleanups from Daniel Lezcano.

 - devfreq updates from Nishanth Menon and others.

 - cpupower update from Thomas Renninger.

 - Fixes and small cleanups all over the place.
