Yeah, I realised what you meant after sending my reply ;).

The arm64 maintainers won't proactively pick these patches up unless we
are asked by the MPAM maintainers. I don't mind whether the patches go
in via the arm64 or Greg's drivers tree. We just queued the first drop
as it touched arm64.

Let's see how it goes but I know little about MPAM, so just being on cc
won't make much difference. I rely on the current MPAM maintainers to
tell me what to merge.

Thanks.
