Here it goes (below). Also do you think you would be able to merge the
driver (corresponding v4 patch follows) in the 3.2 merge window that
seems to have just opened?

[PATCH v5 00/10] virtio DMA API, yet again
This switches virtio to use the DMA API on Xen and if requested by
module option.
This fixes virtio on Xen, and it should break anything because it's
off by default on everything except Xen PV on x86.
To the Xen people: is this okay? If it doesn't work on other Xen
variants (PVH? HVM?), can you submit follow-up patches to fix it?
To everyone else: we've waffled on this for way too
