+	* vm/vm_resident.c (vm_page_external_count): Define variable.
+	(vm_page_grab): New argument `external'.  All callers changed.

+	non-privileged threads exceed the externally-managed page limit.
+	(vm_page_grab_contiguous_pages): New argument `external'.  All
+	callers changed.  Keep track of number of externally managed
+	pages.  Don't let non-privileged threads exceed the
+	externally-managed page limit.
+	(vm_page_convert): New argument `external'.  All callers changed.
+	(vm_page_release): New argument `external'.  All callers

+	that we care about.
