[REGRESSION] AppArmor module parameter layout changed with c5459b829b716

[David Rheinsberg]

Hi

A recent commit changed how `/sys/module/apparmor/parameters/enabled`
looks. It was "Y"/"N" before, now it is an integer. I *think* the
commit that changed this was:

commit c5459b829b716dafd226ad270f25c9a3050f7586
Author: Kees Cook <keescook at chromium.org>

    LSM: Plumb visibility into optional "enabled" state

I haven't recompiled with a revert, but changing the module-parameter
type looks like the obvious culprit. I don't see how this change can
be safe?

This breaks the AppArmor detection of `dbus-broker`. Can the commit be reverted?

Thanks
David
