Merge branches 'clockevents/4.4-fixes' and 'clockevents/4.5-fixes' of http://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
Pull in fixes from Daniel Lezcano: - Fix the vt8500 timer leading to a system lock up when dealing with too small delta (Roman Volkov) - Select the CLKSRC_MMIO when the fsl_ftm_timer is enabled with COMPILE_TEST (Daniel Lezcano) - Prevent to compile timers using the 'iomem' API when the architecture has not HAS_IOMEM set (Richard Weinberger)
