[bisected] Strange slowdowns timerfd related

I've tested the latest git-kernel today and did experience long delays
in Firefox. Just opening a new tab would take a few seconds and after
typing a few characters into the "awesome bar" I would have to wait ages
before the results were shown.

This is the bisection result:

commit 9ec2690758a5467f24beb301cca5098078073bba
Author: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

timerfd: Manage cancelable timers in timerfd

Reverting the commit above fixes the problem.
