It enforces GFP_NOIO even though it uses memalloc_noio_{save,restore} which enforces GFP_NOIO at the page allocator level automatically (via memalloc_noio_flags). It also uses __GFP_REPEAT for the __vmalloc request which doesn't make much sense either because vmalloc doesn't rely on costly high order allocations. Let's just drop the __GFP_REPEAT and leave the further cleanup to later changes.
