So it sounds like Arnd knows what the distros have.
Because I think that would actually be the best way to try to
determine where we want to go, because it's what is going to determine
what is most problematic for _users_.
If no distro is on 4.5, then there's no reason to pick that. The
reason I mentioned 4.5 is because that's the "asm goto" point, afaik,
and that is likely to be a requirement in the near future.
If SLES11 is 4.3, that's obviously a concern. Although Arnd seemed to
imply that that had already caused problems, so...
