Okay, sorry about that. If I promise to fix that in mainline, will you
let me apply the -stable patch?

...I believe this one should go in. Documentation problem is not that
bad, and it fixes booting. 

Alternatively, I can submit fixed patch, but it will be in trivial way
different from what is currently in mainline... which is okay for this
I guess.

Greg, will you take the patch as-is, or can you simply replace - with
: or do you want me to submit new one?
