Make the amd64 pmap (more) mpsafe by protecting both the pmap itself and the
pv lists with a mutex. Rearange some code to avoid sleeping/spinning with
one of these locks held, and also take care that we don't allocate/free
any memory in that case. This should make pmap_enter(9), pmap_remove(9) and
pmap_page_protect(9) safe to use without holding the kernel lock.
Other architectures will follow.
