nit: please can you prefix this function with a couple of underscores and/or change its name? It's now a low-level helper and trusts the caller to pass in a TLBI command, so we really don't want people to call it directly! Anyway, the series looks good to me. In fact, I tried to apply it but I get a conflict with the last patch. Please can you rebase onto my for-joerg/arm-smmu/updates branch? If you do that (plus the nit above) then I can queue these right away.
