Andy, this is the next and hopefully last version. Seems to work fine when replacing the previous patches in your tree. I have some reviews/acks for patch 2 and 3. patch 1 still needs one ack. Can you replace the patches in your tree and carry them along with your changes? old introduction: ----- There are some attempts to unify the dma ops (Christoph) as well as some attempts to make virtio use

here is the 2nd version of providing an DMA API for s390. There are some attempts to unify the dma ops (Christoph) as well as some attempts to make virtio use the dma API (Andy). At kernel summit we concluded that we want to use the same code on all platforms, whereever possible, so having a dummy dma_op might be the easiest solution to keep virtio-ccw as similar as possible to

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
