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
