From: Arnd Bergmann <arnd@xxxxxxxx> Division of 64-bit values causes a link failure on 32-bit targets, depending on compiler version and target architecture: ERROR: modpost: "__divdi3" [sound/pci/emu10k1/snd-emu10k1.ko] undefined! ERROR: modpost: "__udivdi3" [sound/pci/emu10k1/snd-emu10k1.ko] undefined! Replace these with the safe div_u64() helpers.
