A fixed version of this patch is the last thing I'm waiting on before
sending my final -rc pull request to Linus.  I would skip this, but
since the IPoIB fixes broke things, we need a proper version of this
patch to undo that breakage.  I fixed it up as I saw fit and sent the
fixed version to the list on its own thread, please double check it
before I send it to Linus.
