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. -- Catalin
