ARM: 8771/1: kprobes: Prohibit kprobes on do_undefinstr
commit eb0146daefdde65665b7f076fbff7b49dade95b9 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: 24ba613c9d6c ("ARM kprobes: core code")
