| H A D | getuser.S | 0d73c3f8 Sat May 12 23:04:29 CDT 2018 Masami Hiramatsu <mhiramat@kernel.org> ARM: 8772/1: kprobes: Prohibit kprobes on get_user functions
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.
