[PATCH 06/19] arc: get rid of superfluous __GFP_REPEAT

[Michal Hocko <mhocko@kernel.org>]

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.

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.
