From: Vladimir Murzin Date: Mon, 4 Sep 2017 08:17:48 +0000 (+0100) Subject: ARM: 8696/1: mm: Remove dead code in mem_init() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0d9ac1625ac1041742c72c3b680198f0304539b2;p=openwrt%2Fstaging%2Fblogic.git ARM: 8696/1: mm: Remove dead code in mem_init() The code in question checks memory constrains to set default policy for overcommit; however we support page size of 4K only thus condition is always evaluated to false. Remove that dead code.
