Not really. It's just a transitional thing. As you said, you know
perfectly well that modern Linux drivers like iwl3945 handle their
firmware separately through request_firmware() rather than including it
in unswappable memory in the static kernel. We're just updating some of
the older drivers to match.

I've often managed to configure a kernel which doesn't boot, when I've
updated and not paid attention to the questions which 'oldconfig' asks
me. It's fairly easy to do. But I don't advocate that 'allyesconfig'
should be the default, just in case someone needs one of the options...

But as I said, I'm content to let Linus make that decision. In the
meantime, I'd prefer to get back to the simple business of updating
drivers to use request_firmware() as they should, and have maintainers
actually respond to the _patches_ rather than refusing to even look at
the code changes because they disagree with the default setting for the
