From: Michal Hocko <mho...@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.
pte_alloc_one_kernel uses __get_order_pte but this is obviously
always zero because BITS_FOR_PTE is not larger than 9 yet the page
size is always larger than 4K. This means that this flag has never
been actually useful here because it has always been used only for
PAGE_ALLOC_COSTLY requests.
