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
