Hmm. Why is that whole cpu_clock stuff in place anyway? powerpc has
perfectly synchronised time across processors with dirt cheap access to
it as well, so why build all this code that only messes it up on top of
it?

Same on sparc64.  These changes add more bugs than they fix.

I tend to think all this clock business should be done local to those
arches that aren't capable of providing cheap, useful synchronised and
accurate clocks themselves. Or be a lib that they can link in if needed.
As it stands, it seems to me that it all just penalises those
architectures that have decent clocks.
