I think that if we cover x86-64 and plain old x86 with something like "allmodconfig", and just doing a best effort on the other architectures, we're already in pretty damn good shape. It's not like fixing any stupid left-overs that got missed because some "grep" pattern didn't notice an odd user is going to really cause problems. I don't think the architecture maintainers will have any trouble converting their own architecture. It's literally a question of getting clear compiler warnings or errors, and just fixing them up. I'll do at least the parts of ppc64 that I'd notice myself, unless somebody else just gets to it first. So I really wouldn't worry about any small short-term problems. The reason I mentioned out-of-tree drivers is exactly the fact that they can't just fix it up trivially for a single flag-day, so they have to have a longer- term solution.
