Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer core updates from Thomas Gleixner: "The time(r) departement provides: - more infrastructure work on the year 2038 issue - a few fixes in the Armada SoC timers - the usual pile of fixlets and improvements" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource: armada-370-xp: Use the reference clock on A375 SoC watchdog: orion: Use the reference clock on Armada 375 SoC clocksource: armada-370-xp: Add missing clock enable time: Fix sign bug in NTP mult overflow warning time: Remove timekeeping_inject_sleeptime() rtc: Update suspend/resume timing to use 64bit time rtc/lib: Provide y2038 safe rtc_tm_to_time()/rtc_time_to_tm() replacement time: Fixup comments to reflect usage of timespec64 time: Expose get_monotonic_coarse64() for in-kernel uses time: Expose getrawmonotonic64 for in-kernel uses time: Provide y2038 safe mktime() replacement time: Provide y2038 safe timekeeping_inject_sleeptime() replacement time: Provide y2038 safe do_settimeofday() replacement time: Complete NTP adjustment threshold judging conditions time: Avoid possible NTP adjustment mult overflow. time: Rename udelay_test.c to test_udelay.c clocksource: sirf: Remove hard-coded clock rate
