From: Michal Hocko Date: Fri, 24 Jun 2016 21:49:25 +0000 (-0700) Subject: unicore32: get rid of superfluous __GFP_REPEAT X-Git-Tag: v4.14-rc1~2980^2~22 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a830627b01b26452a13abb7e7b37d39365be4b05;p=platform%2Fkernel%2Flinux-rpi.git unicore32: get rid of superfluous __GFP_REPEAT __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. PGALLOC_GFP uses __GFP_REPEAT but it is only used in pte_alloc_one, pte_alloc_one_kernel which does order-0 request. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
