Message-Id: <1351022666-6960-8-git-send-email-keescook@chromium.org> Date: Tue, 23 Oct 2012 13:01:20 -0700 From: Kees Cook <keescook@...omium.org> To: linux-kernel@...r.kernel.org Cc: Kees Cook <keescook@...omium.org>, Russell King <linux@....linux.org.uk> Subject: [PATCH 007/193] arch/arm: remove CONFIG_EXPERIMENTAL This config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it.
