Yes and no. This prevents the oops from happening. However, the
reason this check is necessary is that earlier on the AppArmorFS
failed to be created. The creation failed because a directory
"apparmor" could not be created in the root directory of the
"securityfs".

I believe that this is due to a platform configuration issue. However,
I'm trying to figure out what the "securityfs" is, how it gets
created and why it is missing from the imx51.
