Then why didn't this new config option default to "Y" for a while (say a year or two) before changing the default to off? That would have prevented people like Paul from running into the problem when running "olddefconfig". I think that is what Linus would have wanted in a case like this, but might be totally wrong there (I CCed him, in case he wants to share his opinion, but maybe he does not care much). But I guess that's too late now, unless we want to meddle with config option names. But I guess that might not be worth it after half a year for something that only causes a warning (aiui).
