I've tested that branch by running some random guests without noticeable
problems and by testing X86CPU level/xlevel simplifications on top
(attached).

NOTE: There is a v6 patch with fixed commit message hidden as reply
within this series but there is no matching -v6 branch pushed yet.

That being said, v5 series
