x86/traps: Mark do_int3() NOKPROBE_SYMBOL
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: 21e28290 ("x86/traps: Split int3 handler up") Signed-off-by:Li Huafei <lihuafei1@huawei.com> Signed-off-by:
