#     Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull core timer updates from Thomas Gleixner:
#      "Timers and timekeeping updates:
#     
#        - A large overhaul of the posix CPU timer code which is a preparation
#          for moving the CPU timer expiry out into task work so it can be
#          properly accounted on the task/process.
#     
#          An update to the bogus permission checks will come later during the
#          merge window as feedback was not complete before heading of for
#          travel.
#     
#        - Switch the timerqueue code to use cached rbtrees and get rid of the
#          homebrewn caching of the leftmost node.
#     
#        - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
#          single function
#     
#        - Implement the separation of hrtimers to be forced to expire in hard
#          interrupt context even when PREEMPT_RT is enabled and mark the
#          affected timers accordingly.
#     
#        - Implement a mechanism for hrtimers and the timer wheel to protect
#          RT against priority inversion and live lock issues when a (hr)timer
#          which should be canceled is currently executing the callback.
#          Instead of infinitely spinning, the task which tries to cancel the
#          timer blocks on a per cpu base expiry lock which is held and
#          released by the (hr)timer expiry code.
#     
#        - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
#          resulting in faster access to timekeeping functions.
#     
#        - Updates to various clocksource/clockevent drivers and their device
#          tree bindings.
#     
#        - The usual small improvements all over the place"
