Merge master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq
* master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq: Move workqueue exports to where the functions are defined. [CPUFREQ] Misc cleanups in ondemand. [CPUFREQ] Make ondemand sampling per CPU and remove the mutex usage in sampling path. [CPUFREQ] Add queue_delayed_work_on() interface for workqueues. [CPUFREQ] Remove slowdown from ondemand sampling path.
