Well, the alternative is that you go back to patching your own kernel, and
we drop this patch altogether.

The compromise was to add this notice, to make sure that this doesn't get
set normally.

Changing the wording is fine, but to keep the option from being "forgotten
about" by a indiscrete message isn't going to fly.
