From: Michal Hocko <[email protected]> __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.
arch_dup_task_struct uses __GFP_REPEAT for fpu_regs_size which is either sizeof(__vector128) * __NUM_VXRS = 4069B resp. sizeof(freg_t) * __NUM_FPRS = 1024B AFAICS. page_table_alloc then uses the flag for a single page allocation. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
