When i386 kernel is compiled without CONFIG_X86_LOCAL_APIC, this happens:

In file included from arch/i386/kernel/traps.c:51:
include/asm/nmi.h:46:1: warning: "trigger_all_cpu_backtrace" redefined

This is because x86_64-mm-all-cpu-backtrace.patch makes
trigger_all_cpu_backtrace to be defined twice in such case. This fixes it.
