0bf9195444 Erase kernel PTEs in pmap_page_protect4m(). This bug would leave spurious 
entries in the kernel address space, eventually leading to panics in
pv_unlink().   This takes care of PRs 3575 & 3703.

ea87baf550 Since all kernel regions are pre-allocated, we can safely copy kernel 
mappings to a user pmap when it's created rather than at context
allocation time.  Also, do not copy the kernel's region administration
to every user pmap, especially since no memory appears to be allocated
to copy it into.

As a result of this, we must now switch to context 0 in both pmap_copy_page()
and pmap_zero_page() (XXX).
