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"
