Will Deacon 05cbaf4ddd iommu/arm-smmu-v3: Document ordering guarantees of command insertion ... It turns out that we've always relied on some subtle ordering guarantees when inserting commands into the SMMUv3 command queue. With the recent changes to elide locking when possible, these guarantees become more subtle and even more important. Add a comment documented the barrier semantics of command insertion so that we don't have to derive the behaviour from scratch each time it comes up on the list.
