...a list of pointer ops, but I find this solution terrible. If virtio or virtio_mmio is a module, virtio-iommu also needs to be one. The minimal set of changes to make a module out of an OF-based IOMMU driver seems to be: * Export IOMMU symbols used by drivers * Don't give up deferring probe in of_iommu * Move IOMMU OF tables to .rodata * Create a static virtio-iommu stub that declares the virtio-iommu OF table entry.

Implement the virtio-iommu driver following version 0.6 of the specification [1]. Previous version, RFCv2, was sent in November [2]. This version addresses Eric's comments and changes the device number. (Since last week I also tested and fixed the probe/release functions, they now use devm properly.) I did not include ACPI support because the next IORT specifications isn't ready yet (even
