It's just the trivial extension of the code already in kernel/time.c to
the 64-bit case.

However, it looks like in your case the scaling factor stime/total is
dynamic.  This means that doing scaling by multiplication isn't practical.

I guess I don't understand what function the scaling is supposed to
serve there.
