Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner: "A few fixes for timekeeping and timers: - Plug a subtle race due to a missing READ_ONCE() in the timekeeping code where reloading of a pointer results in an inconsistent callback argument being supplied to the clocksource->read function. - Correct the CLOCK_MONOTONIC_RAW sub-nanosecond accounting in the time keeping core code, to prevent a possible discontuity. - Apply a similar fix to the arm64 vdso clock_gettime() implementation - Add missing includes to clocksource drivers, which relied on indirect includes which fails in certain configs. - Use the proper iomem pointer for read/iounmap in a probe function" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arm64/vdso: Fix nsec handling for CLOCK_MONOTONIC_RAW time: Fix CLOCK_MONOTONIC_RAW sub-nanosecond accounting time: Fix clock->read(clock) race around clocksource changes clocksource: Explicitly include linux/clocksource.h when needed clocksource/drivers/arm_arch_timer: Fix read and iounmap of incorrect variable
