I don't need you to push the patches to the mailing list based on
James's series. I was just asking you to try building locally on top
of the refactoring changes. You are putting in the effort trying to
make this code portable (i.e., inventing new
resctrl_arch_-interfaces), so it would be sensible to check your work
locally.

However, I am the main stakeholder who cares about MPAM and ABMC
working in the same kernel, so I can continue to give feedback on
portability as I compose the series' together.
