Hi x86 maintainers,
This is an important fix that I believe needs to be merged for 4.21. Without it, applications calling fork() can potentially double-allocate a protection key, causing lots of strange problems.
Thomas's Reviewed-by is on the the actual fix, but not the selftest.
I would also be happy to send this as a pull request if you would prefer.
