I'm on vacation now, I can't test it until I'm back, but that
looks quite good overall (except maybe the MacOS-like constant
naming for kXXXX :)

However, does it work with more than 2 CPUs ? It seem to be rather
dual CPU centric from my understanding of the ack mecanism... The TB sync
code is also used on 4 CPU daystar machines and possibly some other chrp
with more than 2 CPUs.

Paul, any comment ?
