From: Michal Hocko Date: Fri, 24 Jun 2016 21:49:22 +0000 (-0700) Subject: tile: get rid of superfluous __GFP_REPEAT X-Git-Tag: v4.7-rc5~11^2~23 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=f45eebc25e78991ef6a6d784ab54151d3003cfdf;p=linux.git tile: 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. pgtable_alloc_one uses __GFP_REPEAT flag for L2_USER_PGTABLE_ORDER but the order is either 0 or 3 if L2_KERNEL_PGTABLE_SHIFT for HPAGE_SHIFT. This means that this flag has never been actually useful here because it has always been used only for PAGE_ALLOC_COSTLY requests.
