Log Message:
Set normal memory PTEs with PTE_M (memory coherent).  Change how we
remember the "exec"ness of a page.  If a managed page is pmap_enter'ed
with VM_PROT_EXECUTE, remember that it's an "exec"page.  Such that when
additional mapping are performed, no synch'ing of the I-cache is needed.
Revoke "exec"ness when the page is mapped into the kernel with VM_PROT_WRITE
or the pmap_page_protect is called with VM_PROT_NONE.
