I interpreted Thomas and Peter's responses to mean that there are no
objections for this to be included in v4.19 as a fix.

If I understand the tip branches correctly the core patch seems to be
headed to v4.19 while the rest (excluding the final patch
"x86/intel_rdt: Re-enable pseudo-lock measurements") are headed to v4.20.

Have you decided against including this into v4.19 or did I
misunderstand the responses and/or branches?

Thank you for helping me to sort this out

Reinette
