I think adding the "memory" clobber should be .26 and even -stable. We
know for sure newer gcc will re-order things, we know it for sure some
drivers will break in subtle ways because of that, ad we know as well
that sticking "memory" clobber in there will fix that breakage we know
about ... So I don't see the point of waiting.
