	src/sys/vm: pmap.h
Log Message:
Add an optional pmap hook, pmap_fork(), to be called at the end of
uvmspace_fork().

pmap_fork() is used to "fork a pmap", that is copy data from one pmap
to the other that is NOT related to actual mappings in the pmap, but is
otherwise logically coupled to the address space.
