Merge branch 'x86-timers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 timer updates from Thomas Gleixner:
 "A rather large series consolidating the HPET code, which was triggered
  by the attempt to bolt HPET NMI watchdog support on to the existing
  maze with the usual duct tape and super glue approach.

  This mainly removes two separate partially redundant storage layers
  and consolidates them into a single one which provides a consistent
  view of the different HPET channels and their usage and allows to
  integrate HPET NMI watchdog support (if it turns out to be feasible)
  in a non intrusive way"
