Ok, let's make it constructive. I think there is part of your
implementation that definitely makes sense (in particular the way you
cleaned-up the x86 MCFG unadulterated mess - patch 1), I will ask
Tomasz to integrate it, please work together on this.

I have nothing against your patchset, my point is that we can't keep
reviewing and testing two series (and I mean on ARM64 AND x86), please
understand my point, it is very time consuming to understand the
differences and make sure we don't break x86 in the process and I would
have to ask you to add all the code that I already reviewed in Tomasz's
set, I just do not want to do that.

I will reply to Tomasz, let's work together to have a single final
implementation please, I do not think I am asking too much here and
yes, by integrating part of your code I think Tomasz's patchset is
ready to go, obviously subject to Bjorn's review and opinion.

Thanks,
Lorenzo
