Great debugging :-)
LGTM, at this point I'd merge them:
static int
round_and_check(const struct vm_map *map, vaddr_t *addr, vsize_t *size)
{
const vsize_t pageoff = (vsize_t)(*addr & PAGE_MASK);
*addr -= pageoff;
if (*size != 0) {
*size += pageoff;
*size = (vsize_t)round_page(*size);
}
if (*addr + *size < *addr)
return ENOMEM;
// Make range_test() take const map as it should have in the first place
return range_test(map, *addr, *size, false);
}
