These are the remaining bits implementing iommu_sva_bind_device() for SMMUv3. They didn't make it into v5.10 because an Ack was missing for adding the PASID field to mm_struct. That is now upstream, in commit 52ad9bc64c74 ("mm: Add a pasid member to struct mm_struct"). No change since last posting [1], only rebased onto v5.10-rc2.
Note that full SVA support for SMMUv3 still needs IOPF and DVM support, coming soon.
