It is based on the assumption that every pci_dev that points to the same zpci_dev shares a single dma-table (and thus a single address space). If this assupmtion is true (as it looks to me from reading the code) then the iommu-group setup code in the s390 iommu driver needs to be updated. These patches do this and also add support for the iommu_device_register interface to the s390 iommu driver. Any comments and testing appreciated.
