Prohibit probing on the functions called before kprobe_int3_handler() in do_int3(). More specifically, ftrace_int3_handler(), poke_int3_handler(), and ist_enter(). And since rcu_nmi_enter() is called by ist_enter(), it also should be marked as NOKPROBE_SYMBOL. Since those are handled before kprobe_int3_handler(), probing those functions can cause a breakpoint recursion and crash the kernel.
