As name implies, can this move to intel-iommu.h?
I also thought about this but the masks are in vendor specific part of
the UAPI.
I looked through this patch series. It looks good to me. I will do some
code style cleanup and take it to v5.7. I am not the right person to
decide whether include/uapi/linux/iommu.h is the right place for this,
so I will move it to Intel IOMMU driver for now.
Best regards,
