Hi S/390 PCI and IOMMU maintainers, We've recently tried to convert all implementations of the IOMMU API to use drivers/iommu/dma-iommu.c instead of their local IOMMU ops. I've looked at S/390 and while some comments mention things about the iommu API the implementation looks quite separate. Do arch/s390/pci/pci_dma.c and drivers/iommu/s390-iommu.c driver the same hardware? If so would a switch to drivers/iommu/dma-iommu.c be feasibel?
