Hi Robin, >>Apologies for crossed wires, but I had a series getting rid of arm_smmu_flush_ops which was also meant to end up making things a bit easier for you: I was looking to rebase on top of your changes first. Then I read Will's reply that said your work is queued for 5.5. Let me know if these patches need to rebased on top of iommu/devel or a different branch. I can resend the patch set on top of necessary branch. -KR
