Excellent stuff :)
Currently I'm working on the pmap to figure out where I can improve things.
Looking at the i386 pmap it's got a lot of useful things/ideas that may well
appear in the arm32 pmap. It seems that the rewrite of it for UVM may have
done wonders for it, I know that the arm32 pmap was based on the i386 pmap
from years back, and mark said it was the wrong choice, now it appears that
it might be the right choice. However first I'm going to track down why we
take so long in a fork exit process

The thing is that every arm arch has it's own version of initarm, certainly
some features should be portable to others though, so certainly mail around
about any updates/things you find, see if we can use them elsewhere :)
