Subject: [PATCH 0/3] Cleanup ADJ_SETOFFSET patch

I was looking to queue Richard's ADJ_SETOFFSET patch to see
if it could be merged into -tip for 2.6.38, but on second 
glance I noticed the ugly local_irq_disable bits as well
as the fact that adding the offset uses a gettime/add/settime
pattern which will also add a small error as the action isn't
atomic.

So I implemented a timekeeping function to add a fixed offset:
timekeeping_inject_offset(), and reworked Richard's code to
make use of it.

Richard: Any objection here? Mind testing this with the rest
of your patch queue?

Thomas: Any comments? Does this seem reasonable for 2.6.38? 
Should I fold my cleanups into Richard's patch?

thanks
-john
