Masami Hiramatsu 5f3ca3928e ARM: 8771/1: kprobes: Prohibit kprobes on do_undefinstr 
commit eb0146daef upstream.

Prohibit kprobes on do_undefinstr because kprobes on
arm is implemented by undefined instruction. This means
if we probe do_undefinstr(), it can cause infinit
recursive exception.

Fixes: 24ba613c9d ("ARM kprobes: core code")
