How was this tested, and what do the maintainers of this subsystem think? And will you be around to fix the bugs in this when they are found?
This has been trivial to reproduce, I've used a small repro which I've put here: https://gist.github.com/bgaff/9f8cbfc8dd22e60f9492e4f0aff8f04f , I also was able to reproduce this using the protection_keys self tests on a 11th Gen Core i5-1135G7.
I've got an i7-1165G7, but I'm not seeing any failures on a 5.11 distro kernel.
How long does this take for you to reproduce?
It reproduces for me in just a few seconds. I'm not sure what could be different about my setup, I've tested on a vanilla 5.10 kernel and it reproduced the same way.
