alc aae81a61cf Correct a long-standing race condition in vm_fault() that could result in a
panic "vm_page_cache: caching a dirty page, ...": Access to the page must
be restricted or removed before calling vm_page_cache().  This race
condition is identical in nature to that which was addressed by
vm_pageout.c's revision 1.251 and vm_page.c's revision 1.275.
