From: Michal Hocko<mhocko@xxxxxxxx> __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. pgtable_alloc_one uses __GFP_REPEAT flag for L2_USER_PGTABLE_ORDER but the order is either 0 or 3 if L2_KERNEL_PGTABLE_SHIFT for HPAGE_SHIFT. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
