[PATCHv2 0/3] dma ops and virtio
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
