This doesn't build on my tree, due to HRTIMER_MODE_REL_SOFT not
existing. Neither does HRTIMER_MODE_SOFT mentioned above, but that's
just a commit log mistake.
(It also didn't apply on my tree, but that was a trivial context
change.)
I don't understand why you initialize it with HRTIMER_MODE_ABS_SOFT
either though:

> + HRTIMER_MODE_ABS_SOFT);
shouldn't that already be REL?
