Li Huafei 1fbafa9a5b x86/traps: Mark do_int3() NOKPROBE_SYMBOL 
commit a365a65f9ca1ceb9cf1ac29db4a4f51df7c507ad upstream.

Since kprobe_int3_handler() is called in do_int3(), probing do_int3()
can cause a breakpoint recursion and crash the kernel. Therefore,
do_int3() should be marked as NOKPROBE_SYMBOL.

Fixes: 21e28290b3 ("x86/traps: Split int3 handler up")
