Hey Juergen,

These look great. Thanks for doing it!

The only wonky thing is how we're going to actually merge it. We
obviously can't do patches 10-11 until all the "stop using" patches have
been applied.

I obviously 100% realize that it's during the merge window, but any acks
that the maintainers of 5-9 provide in the next few weeks would be super
helpful. Or, if any of those maintainers want to cherry pick their
subsystem's stuff out of this series and apply it, that would be great too.

But, the last time we did some MSR function munging, the tip tree
carried most of the patches. I would expect we'll have a repeat of that
here too. I'll pencil in the idea of just merging the lot around -rc1 time.

Note, patch 12 "treewide: convert rdmsrq() from a macro to an inline function"
is going to conflict with the KVM changes for 7.3; kvm_access_xstate_msr() is
getting moved from x86.c to msrs.c.  Somewhat surprisingly, AFAICT that's the
only conflict with KVM's code movement, so it's probably not strictly required
to send a new version after the KVM pull request?
