ARC: fix build warnings with !CONFIG_KPROBES

| CC lib/nmi_backtrace.o | In file included from ../include/linux/kprobes.h:43:0, | from ../lib/nmi_backtrace.c:17: | ../arch/arc/include/asm/kprobes.h:57:13: warning: 'trap_is_kprobe' defined but not used [-Wunused-function] | static void trap_is_kprobe(unsigned long address, struct pt_regs *regs) | ^~~~~~~~~~~~~~ The warning started with 7d134b2 ("kprobes: move kprobe declarations to asm-generic/kprobes.h") which started including <asm/kprobes.h> unconditionally into <linux/kprobes.h> exposing a stub function for !CONFIG_KPROBES to rest of world. Fix that by making the stub a macro Signed-off-by: Vineet Gupta <[email protected]>
