x86 doesn't need a 3.1 machine type, because there's no incompatibility,
but it looks odd not having one, especially since s390, ppc and ARM have
it.  Join the party.

OK, the problem is it's buried in the middle of a big series; can we
just take either this version or your version for 3.1?

Could you post that as a standalone patch marked as for-3.1 please?
Then we can put it into the release without having to manually
fish it out of a big patchset.
