[PATCH v2 0/2] cpufreq support for the big.LITTLE switcher

This is the third and final set of patches towards a fully functional and production quality switcher solution for big.LITTLE systems, establishing a landmark to compare against for any scheduler based solution meant to eventually surpass the switcher's power efficiency available in the mainline kernel.

Rationale for this code: http://lwn.net/Articles/481055/

The first and second patch sets have already been merged by RMK. They implement the core switcher mechanism. This set adds the necessary code to drive the switcher based on cpufreq governor decisions.

This set (v2) was rebased on top of the latest linux-pm tree as requested by Rafael.
