Holy crap, this is great! Are you able to look at what it'd take to bring this up on -HEAD? Have a chat with Alan about the VM changes; he should be able to help you figure out what's changed in -HEAD and what needs to be polished before this thing can be committed. How do you suggest this is tested/evaluated?

I probably messed something up = in the rebase, as lots of things changed both in pmap and vm since 9.1. Th= ere are also a handful of commits that i haven't gotten to yet, but they ar= e less consequential - just performance improvements to the buddy allocator= .
