Actually, no - we do need a version of the fix for older versions prior
to the kernel having pointer auth support since the goal was to ensure
that the kernel doesn't actually get built with pointer auth when we are
doing it for userspace as that leaves us with half baked pointer auth in
the code. The original fixes was right and we want a redone backport.
