Really, this series and that series must be together. We have a patch

I'm thinking strongly about moving the nesting code into
arm-smmuv3-nesting.c and wrapping it all in a kconfig. Similar to
SVA. Now that we see the viommu related code and more it will be a few
hundred lines there.

We'd leave the kconfig off until all of the parts are merged. There
are enough dependent series here that this seems to be the best
compromise.. Embedded cases can turn it off so it is longterm useful.

WDYT?
