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.
