I don't know what the plan is to get this series upstream. Joerg, would you expect this to go via your tree or via something broader like arm-soc, with your Ack on the IOMMU bits (patches 1, 3 and 4) instead? I certainly don't see why patches 1-5 couldn't be queued, then we could add the ARM bits later. I just need to know where to send them!
