Hmm, I don't like the idea of storing private data in iommu_ops. But given that this is already an improvement we can build on later, here is my Acked-by: Joerg Roedel To further improve this we should probably introduce a seperate iommu-descriptor data-structure later which then describes a single hardware iommu device.
