| hi i am writing a kernel 2.4.x driver and need to do maths on 64 bit ints
| (unsigned long long)
| bcause you can not use the FPU
| but when i insmod i get the error unresolved symbol __udivdi3 i need!! 64
| bit ints
Other alternatives are search the lkml archive for a patch from
George Anzinger on 2003-mar-05,
subject: [PATCH] Functions to do easy scaled math.
or if all you need is 64-bit mul and div, and only during setup
(when speed isn't a huge factor), you could use the divrem64()
function in this sample /procfs module:
