With the latest kmemleak changes which I pushed to Linus they disappeared. I missed the kmalloc_large in slub and probably some of the root objects that keep references to others weren't scanned (maybe the kzalloc call in wiphy_new was missed as it links to all the bulk of the reported objects in the iwlwifi code).
