Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer fixes from Thomas Gleixner:
 - Fix inconstinant clock usage in virtual time accounting
 - Fix a build error in KVM caused by the NOHZ work
 - Remove a pointless timekeeping duty assignment which breaks NOHZ
 - Use a proper notifier return value to avoid random behaviour

* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  tick: Remove useless timekeeping duty attribution to broadcast source
  nohz: Fix notifier return val that enforce timekeeping
  kvm: Move guest entry/exit APIs to context_tracking
  vtime: Use consistent clocks among nohz accounting
