In my local repository I modified my .config file so that CONFIG_64BIT is not set, and after that I recompiled all directory, but I don't get any errors/warning at compile-time. Also I separetly compiled this specific file but still no warnings My .config looks something like this:

Should I change my working kernel or .config file is just enough?
I think the problem is that you only compiled that directory but did not attempt to do a full rebuild of the kernel and modules, which is required to catch link-time errors.
The compiler does not know at this point that the 64-bit division function is undefined in the kernel, you only get a warning at the 'make vmlinux' link stage (for built-in drivers) or the 'make modules' modpost stage afterwards.
