[PATCH v2 00/16] x86/msr: Cleanup and FRED prep

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

This started as the final couple of patches, and escalated...

Some has been posted before, two even back in 2018 (work literally done in
Nanjing airport leaving XenSummit, and there was an 8h delay).  The rest is
FRED prep work, targetted for 4.21.
