WoooHooo!! It is finally out there, after roughly 4 months of juggling with uvm code base and testing. Cherry (cherry@) has made the final commit into the NetBSD-CURRENT branch the changes related to uvm_hotplug(9).

Each of these commits could be completely rolled back without affecting the previous commits. This is a good practice that I got to see in action from Cherry.
We also came up with a port-masters’ FAQ which you can read about
