ARM: 8772/1: kprobes: Prohibit kprobes on get_user functions
commit 0d73c3f8e7f6ee2aab1bb350f60c180f5ae21a2c upstream.
Since do_undefinstr() uses get_user to get the undefined
instruction, it can be called before kprobes processes
recursive check. This can cause an infinit recursive
exception.
Prohibit probing on get_user functions.
Fixes: 24ba613c9d6c ("ARM kprobes: core code")
