It's because of this function:

unsigned long os_msec (void) {

	return (((unsigned long long) jiffies) * 1000) / HZ;
} /* os_msec */

It doesn't look very hard to rewrite this not to use division if HZ is
100.  Alternatively, try this:

unsigned long os_msec (void) {

	return (((long long) jiffies) * 1000) / HZ;
} /* os_msec */
