Adding patch author to CC.
Hi Qii Wang,
can you send an incremental patch to replace the 64-bit division with
either do_div() or some apropriate div64_* function?
While there, it might also be good to double check if the divisor is
always non-zero to prevent "division by zero" OOPSes, if you haven't
done this already.
Thanks,
Wolfram
