You may find the vm_map and pmap documentation which I have just submitted to the project helpful for reference:- http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/54691 http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/54632 and ref: our online conversation about the vm_map_insert() semantics (and possible failure mode re: NULL vm_object argument for the user process case).
