Building the kernel with rt-preempt on MPC5121e, I get this one: arch/powerpc/kernel/stacktrace.o: In function `save_stack_trace': arch/powerpc/kernel/stacktrace.c:50: multiple definition of `save_stack_trace' arch/powerpc/kernel/setup_32.o:arch/powerpc/kernel/setup_32.c:328: first defined here Looks like somebody forgot to remove this in setup_32.c; setup_64.c has it removed.
