From: Andreas Herrmann Date: Wed, 6 Aug 2008 14:23:08 +0000 (+0200) Subject: x86: compile pat debugfs interface only if CONFIG_X86_PAT is set X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=012f09e7942716d5f4339f1fd9a831a485bb1d4a;p=openwrt%2Fstaging%2Fblogic.git x86: compile pat debugfs interface only if CONFIG_X86_PAT is set Recently I've run a kernel w/o PAT support and wondered why there was a file "x86/pat_memtype_list" in debugfs. Of course it's empty if PAT is disabled ... so just get rid of this interface if PAT is disabled.
