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 :)
