Yeah, as I've said in private, I now have the patches to make this work,
so this patch (and the later one removing it again) are both gone from
my current dev branch. I'll still wait a day or two to allow the ppc
people to respond to the inline/OOL iowrite32be issue, but after that
I'll resend the whole series.
