Thanks for the patches (and the fuzzing!). They all mostly lgtm, just some small nits. Please fix them so I can test and merge. Also, could you add a Fixes tag to each patch (like in the LKML and elsewhere in OVMF) so we can more easily track what each patch fixes? Using something simple like the oldest git blame of what you're fixing should be enough in this case, no need for git bisect. I just want to establish a good, clean track record here for me and for downstream users to better know what they need to pick up!
