Since this is 90% of the way there now, I suggest Robin picks up what's here
and incorporates his remaining review comments directly (especially since it
sounded like Zhen Lei hasn't got much free time lately). With that, I can
queue this lot via my smmu branch, which already has some stuff queued
for SMMUv3 and io-pgtable.
Please shout if you have any objections, but I'm keen for this not to
languish on the lists given how close it is!
