Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Ingo Molnar:
"This cycle had the following changes:
- Timer tracing improvements (Anna-Maria Gleixner)
- Continued tasklet reduction work: remove the hrtimer_tasklet
(Thomas Gleixner)
- Fix CPU hotplug remove race in the tick-broadcast mask handling
code (Thomas Gleixner)
- Force upper bound for setting CLOCK_REALTIME, to fix ABI
inconsistencies with handling values that are close to the maximum
supported and the vagueness of when uptime related wraparound might
occur. Make the consistent maximum the year 2232 across all
relevant ABIs and APIs. (Thomas Gleixner)
- various cleanups and smaller fixes"
