Merge branch 'nohz/drop-double-write-v3' of git://git.kernel.org/pub/scm/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. " Signed-off-by: Ingo Molnar <mingo@kernel.org>
