Merge branch 'clockevents/4.0-rc1' of git://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
Pull clockevents driver fixes from Daniel Lezcano:
- Fix the Kconfig to prevent the asm9260 timer to be compiled with
allyesconfig with sparc/sparc64 (Daniel Lezcano)
- Reorder the mtk driver init sequence in order to prevent a potential race
when the clock is registered before the irq handler is set (Matthias Brugger)
- Fix a section mismatch for the pxa driver (Robert Jarzmik)
