This ordering is sensible to me. I find the patch breakdown a bit fragmented since
the logical resctrl fs change is split yet I also find that you did what was best
to ensure bisectability. I find small changes that are local to subsystems easier to
consider and believe it would be ideal to only have patches touching multiple
subsystems when it cannot be avoided, for example when doing otherwise would break
bisect. Even so, we may learn of better ways to do this when this series is considered
for x86 inclusion.
