Merge branch 'clockevents/4.0-rc2' of http://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
Pull clockevents fixes from Daniel Lezcano: " These two patches fix a potential crash at boot time. - Fix setup_irq / clockevents_config_and_register init ordering in order to prevent to have an interrupt to be fired before the handler is set for sun5i and efm32. (Yongbae Park)" Signed-off-by: Ingo Molnar <mingo@kernel.org>
