From 39f838e06f46576694d425ac30fe8ff1e214fc0b Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Wed, 30 Oct 2013 14:21:53 +0000 Subject: [PATCH] x86: Drop support for /proc files when !CONFIG_PROC_FS arch/x86/kernel/cpu/proc.c only exists to support files in /proc; omit that file when compiling without CONFIG_PROC_FS.
