    That changes it dramatically. The numbers from the sycall until the
    linked-in module are now down to 15-25 milliseconds, and for a few
    large modules 50-100.

    (One crazy exception is ipv6, which takes 620 milliseconds to link, no
    idea what it needs to do.)

    I'll compare a few bootup times with and without the patch, and come
    back later today with the real numbers.

    Thanks a lot,
