Normally you would have missed the merge window by now, but I'd really
like this stuff in, so I'm holding it open for this.  I want these patches
in linux-next for at least a few days before I push them.

If you think we're not close enough, please tell me and I'll push
the rest of the virtio patches to Linus now.  

Thanks,
Rusty.
