    Suggest a "\n" at the end of that. Maybe add the precomputed value to
    help bring incorrect presets to someone's attention, something like:

    + printk("BogoMIPS preset to %lu.%02lu\n",
    + loops_per_jiffy/(500000/HZ),
    + (loops_per_jiffy/(5000/HZ)) % 100);

    I suppose it may result in unpredictable I/O errors, in case we want to
    warn against that.
