Pull timer fix from Thomas Gleixner:
 "A fix for a long standing issue in the alarmtimer code.

  Posix-timers armed with a short interval with an ignored signal result
  in an unpriviledged DoS. Due to the ignored signal the timer switches
  into self rearm mode. This issue had been "fixed" before but a rework
  of the alarmtimer code 5 years ago lost that workaround.

  There is no real good solution for this issue, which is also worked
  around in the core posix-timer code in the same way, but it certainly
  moved way up on the ever growing todo list"
