- add fields to 'struct pmap' that are required to manage nested page tables. - add a parameter to 'vmspace_alloc()' that can be used to override the default pmap initialization routine 'pmap_pinit()'. These changes are pushed ahead of the remaining changes in 'bhyve_npt_pmap' in anticipation of the upcoming KBI freeze for 10.0. Reviewed by: kib@, alc@ Approved by: re (glebius)
