        As I understand it there are two factors in favour of keeping SA:

        - There was a report of a significant performance gain on single
          core embedded arm32
        - If we keep SA for 5.0 it allows people to run a 4.0 userland
          on a 5.0 kernel while upgrading (and makes COMPAT_40 useful).
