Ok, I've edited the patch to add the 'spoofing' wording where
appropriate, and I also made minor fixes such as consistently
capitalizing instruction names.

Can I also add your Reviewed-by tag?

So the patch should show up in tip:x86/asm today-ish, and barring any
complications is v5.4 material.

Thanks,
