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.
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.
