Otherwise, the module will reference __udivdi3 under 32-bit kernels, which is not allowed in kernel space. drivers/built-in.o: In function `carl9170_collect_tally': cmd.c:191: undefined reference to `__udivdi3' cmd.c:192: undefined reference to `__udivdi3' cmd.c:193: undefined reference to `__udivdi3' Reported-by: Kalle Valo Signed-off-by: Christian Lamparter Tested-by: Kalle Valo Signed-off-by: John W.
