3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kees Cook <keesc...@chromium.org>
commit 3594f4c0d7bc51e3a7e6d73c44e368ae079e42f3 upstream.
The exposed interface for cm_notify_event() could result in the event msg
string being parsed as a format string. Make sure it is only used as a
literal string.
