I don't really have a strong opinion, but I can see the logic at some
level. This patch definitely doesn't _hurt_ and it seems plausible
that a define like this could be used in a future errata. Having this
already in stable would mean that the future errata would just pick
cleanly without anyone having to track down the original patch.
