Exactly, thanks for the clarification. I also didn't realize that there is now an include/linux/iommu.h file that only describes the PCI SR-IOV interfaces, unlike the generic IOMMU support that we have in your include/linux/dma-mapping.h file.
Maybe we should rename linux/iommu.h to something more specific so we can reduce this confusion in the future.
