OK, so the original code of:

    x = (secs * 1000000000ULL) + (u64)nsecs - system_time_base;
    y = do_div(x, 1000000000);

Leaves "x" as the number of seconds and "y" as the
remainder, in nanoseconds.

Good to know that I overlooked something and the
original code was right after all!

All rights reversed.
