[LSM] Kernel panic - not syncing: Could not register security module

Hi Kees,

0day kernel testing robot got the below dmesg and the first bad commit is

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git lsm/mnt-restrict
commit d9df832e0cc059bc6f94ee6ea5286fdd1efac503
Author: Kees Cook <keescook@xxxxxxxxxxxx>
AuthorDate: Sat Sep 21 15:52:51 2013 -0700

LSM: MntRestrict blocks mounts on symlink targets

On systems where certain filesystem contents cannot be entirely trusted,
it is beneficial to block mounts on symlinks. This makes sure that
malicious filesystem contents cannot trigger the over-mounting of trusted
filesystems. (For example, a bind-mounted subdirectory of /var cannot be
redirected to mount on /etc via a symlink: a daemon cannot elevate privs
to uid-0.)
