There is a small build conflict with resctrl abmc precursors, [1]. The
last patch of that series applies on top of this series and if the abmc
precursors go first that patch should go with this series to fix the
build. Alternatively, if it's obvious ahead of time it can be squashed
into pathc 33 with the other empty resctrl arch hooks.
