SubjectRe: [PATCH] x86_64: test that userspace stack is in fact NX

BTW., it's also questionable whether the owner is *aware* of the fact that
NX is not available: what if some kernel debug option cleared the NX flag,
unintended, or there's some serious firmware bug?

However unlikely those situations might be, I think unconditionally warning
about NX not available is a very 2023 thing to do.

Thanks,

Ingo
