From: Michal Hocko <mhocko@suse.com>
__GFP_REPEAT has a rather weak semantic but since it has been introduced around 2.6.12 it has been ignored for low order allocations.
PGALLOC_GFP uses __GFP_REPEAT but {pgd,pmd}_alloc allocate from {pgd,pmd}_cache but both caches are allocating up to PAGE_SIZE objects. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
