In order to save power, it would be useful to schedule light weight work on cpus that aren't IDLE instead of waking up an IDLE one.

By idle cpu (from scheduler's perspective) we mean:

• Current task is idle task
• nr_running == 0
• wake_list is empty

Oops!! I forgot the change log:

V2->V3: - Dropped changes into core queue_work() API, rather create *_on_any_cpu() APIs - Dropped running timers migration patch as that was broken - Migrated few users of workqueues to use *_on_any_cpu() APIs.
