This patchset moves cpufreq callbacks to dpm_{suspend|resume}() from dpm_{suspend|resume}_noirq() for handling suspend/resume of cpufreq governors and core. This is required for early suspend and late resume of governors as there are drivers which want to change cpu frequency before suspending governors and they want to do it before devices get suspended, as some of them might be required to change frequency.
Following patch is already pushed for v3.13 as it was required for fixing some bugs in there. And the remaining was decided to be pushed for v3.14.
