We should probably also ignore and additional registration calls, not just
those made after the delay loop has been calibrated...

Something like the patch below should do the trick.

Cheers, pushed into my delay branch.

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.
