Pull timer fixes from Ingo Molnar:
 "A fix for an abs()/abs64() bug that caused too slow NTP convergence on
  32-bit kernels, plus a removal of an obsolete clockevents driver
  facility after all users got converted during the merge window"

* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  clockevents: Remove unused set_mode() callback
  time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of abs64()
