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)"
