Hi, Cherry!

Currently there are a number of builds broken for reasons related to
pmap/uvm changes:

https://releng.netbsd.org/builds/HEAD/201612240730Z/

You added a new kernel option UVM_HOTPLUG, but I assume you must have
made API changes that go beyond the #ifdef UVM_HOTPLUG parts.

Can you write up a summary of the pmap and uvm API changes you made,
from the perspective of a portmaster, or a portmaster's understudy?
What were a pmap's relevant responsibilities before your changes, and
what are they after?

In addition to fixing the build, it would be helpful to be able to
review changes to fix the build more than cursorily via the autobuild
status.
