MFC revision 1.140
 Eliminate an unnecessary call to vm_page_busy().

MFC revision 1.141
 Pass VM_ALLOC_NOBUSY to vm_page_grab() so that we don't have to call
 vm_page_flag_clear(PG_BUSY).  The object lock is held the entire time.
 Thus, whether or not the PG_BUSY flag is set is invisible to others.

MFC revision 1.145
 Acquire the source pmap's lock in pmap_copy().
