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, Ingo
