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

Pull timer fix from Thomas Gleixner:
 "A single fix to prevent the alarm timer code from returning ENOTSUPP
  to user space.

  ENOTSUPP is a purely kernel internal error code related to NFSv3 and
  should never be handed back to user space. The risk for ABI breakage
  is low as the number of systems which do not have a working RTC is
  very limited"

  alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP
