Leap-second fix for Lucid
 
John Stultz <john.stultz@linaro.org> has put together a patch set to
address the leapsecond bug that was encountered this past weekend by
some sites.

This set has had some testing by a few people and has been accepted
upstreams. However, the 2.6.32 stable tree containing the fix hasn't
yet been published.

The following mailing list thread covers this patch set and the discussions
around them:

And here's the submission of the 2.6.32 backport:
