I don't think this patch can be applied. Building a list and then freeing it was done for some reason, at least because kmem_free, (thus vm_map_delete), may actually need to use zalloc in order to split some areas (which is actually the reason for the double map_entry allocation/release), which thus needs to lock the zone, and thus ends up with a deadlock.
