Thanks for the registration machanism.  It looks nice, and works for
me on a Cortex-A9 SMP platform with a non-arch_timer counter.

I've picked up a revised version of the patch from will/delay and
merged it into our local development branch.  We'll give it a try
in different conditions, UP and SMP, with/without DVFS and so on,
and let you know if I find anything.
