Frederic Weisbecker 19f5f7364a nohz: Separate idle sleeping time accounting from nohz logic 
As we plan to be able to stop the tick outside the idle task, we
need to prepare for separating nohz logic from idle. As a start,
this pulls the idle sleeping time accounting out of the tick
stop/restart API to the callers on idle entry/exit.
