Yes, there's such a function in arch/arm/lib/lib1funcs.S, which in turns requires the __div0 symbol, defined in arch/arm/kernel/traps.c, and this one cannot be used as it brings plenty of symbols that aren't available in the pre-boot environment. So anyway, we have to define our own symbols there. Either we use libgcc and define raise(), or lib1funcs and define __div0(). Russell, what's your take on this ?
