You have a #if 0'd dump_add_page() in get_pv_entry() in pmap.c you probably want to enable (see also the dump_drop_page() in free_pv_chunk().
See also the uma_small routines in uma_machdep.c. amd64 has to add them explicitly since they use direct map addresses and thus aren't found by the KVA loop. The symptoms would be that the dump wouldn't contain small objects (ones that use a slab size of a page).
