Merge branch 'clockevents/4.0-rc2' of... 

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)"
