Here is backport of the leapsecond fixes to 3.4-stable. These are very straight forward, and backported to 3.4.x with no collisions or changes.
This patchset resolve the early hrtimer/futex expiration issue widely seen after the June 30th leapsecond. I've booted and tested this patchset on two boxes and run through a number of leapsecond related stress tests. However, additional testing and review would be appreciated.
