The Kconfig option is still there.  The noautogroup -> autogroup arg
change just makes it off by default (since an on/off switch would have
to be a full move everybody thing post 8323f26ce race fix), so distros
can make it available in their swiss army knife config, but it'll be out
of the way unless specifically asked for by the user at boot.

I can make it default 'on' by removing that arg change if you think
that's the better way to go, but opt in at boot sounded better to me
given there is no runtime on/off switch at all now.
