I believe this requires a do_div on 32 bit arch.
Actually, the "unsigned long long" is a holdover from the
code I had before. With the calculation above, I think I
can make it a simple "unsigned long" and get rid of the
do_div magic alltogether...
Btw, it would help if you could trim your replies. I almost
could not find your one line reply in-between the 1600 lines
of quoted text :)
