Seems sane to me.  There have been quite a few patches I wish I'd been
cc'd on along the way.  I think Andy L in particular is probably way
under-cc'd on x86 stuff in general.

A better long-term solution (that others have suggested) is probably to
create an x86-discuss@vger.kernel.org or something.
