right, not much yet.  the first thing to do is to implement curcpu(),
which I spent a bit of time on a few months back.  the current code
tries to do like the sparc port and use a constant virtual address
with different stuff mapped there on each CPU, but I couldn't manage
to get that to work.  I decided to go for freebsd's approach instead,
putting the curcpu pointer in %g7.  this entails removing all the existing
uses of %g7.  I removed some back then, but there are quite a few left
(all in locore.s at this point).  since then I haven't had much time
for netbsd and I've spent it on other things (softdep bugs and the
sparc64 pmap problems I just fixed).  I would like to get back to
working on sparc64 MP, but if someone else with more time wants to
run with it, that would be fine with me too.
