Merge branch 'clockevents/3.15-fixes' of git://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
clockevent fixes for 3.15 from Daniel Lezcano: * Lorenzo Pieralizi fixed an issue with the arch_arm_timer where the C3STOP flag for all the arch can cause some trouble by setting the flag only if the power domain is not always on * Alexander Shiyan fixed a compilation by changing the init function to the right prototype
