The trigger for this case was tcindex module -- removed in upstream, so
we don't want to have implicit autoloads for it while we retain it in
our distro.

The user has to modprobe explicitly or un-blacklist the module.

(For instance, we've been leveraging this for the fs-* modules due to
various support status of filesystem modules in SLE.)
