I mentioned this before in the original posting. Currently, only the
architected timers are using this interface and I have some reservations
about using memory-mapped timers instead (although there may be specific
instances where they're suitable).

In this case, I'd rather see a registration mechanism for the current_timer
where we take a pointer to read_current_timer and register the delay at the
same time. That can be added when somebody else decides they want to make
use of the new delay routines.

Thanks!
