Yeah, and the GPL specificly invalidates that statement. We're on thin
ice here. Linus is making up the rules, which is cool (since I tend to
like his rules) but the reality is that the GPL doesn't allow you to
extend the GPL. It's the GPL or nothing.

Given the GPL rules you have to disregard Linus' rules that are extensions
and work off of standard law. When you get there it becomes an issue of
boundaries and the law seems to clearly support Linus' point of view, he
didn't need to make that clarification, whether he did or not, that's what
is true in the eyes of the law.

But given that, neither Linus (nor any of you) get to say "well, that's fine
for userland but drivers are derived works".

I've said this over and over and I'll say it again. If you want the
protection of the law you have to live with the law's rules. You DO
NOT get to say "user programs are a boundary across which the GPL does
not apply but drivers are a boundary across which the GPL does apply".
It doesn't, and can't, work that way. Either userland is GPL and drivers
are GPL or neither are GPLed. Take your pick.
