From 397b080bb70f30d6b9778b0e607b67efcf64aa6e Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Tue, 26 Jul 2016 15:20:59 -0700 Subject: arm: 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 none of the allocation which uses this flag is for more than order-2. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
