Merge branch 'nohz/drop-double-write-v3' of git://git./linux/kernel/git/frederic/linux-dynticks into timers/core

Pull nohz fixes from Frederic Weisbecker:

	" The tick reschedules itself unconditionally. It's relevant in periodic
	  mode but not in dynticks mode where it results in spurious double clock
	  writes and even spurious periodic behaviour for low-res case.

	  This set fixes that:

	  * 1st patch removes low-res periodic tick rescheduling in nohz mode.
	    This fixes spurious periodic behaviour.

	  * 2nd patch does the same for high-res mode. Here there is no such
	    spurious periodic behaviour but it still spares a double clock write
	    in some cases. "
