When you do deal with this series could you please also include the
final patch ("x86/intel_rdt: Re-enable pseudo-lock measurements")? I
noticed that patches 1/6 to 5/6 have been merged into x86/cache in
tip.git and then some other work on top of it. It is not clear to me why
6/6 was omitted and this fix does require it.

Thank you very much
