Masami Hiramatsu 365f12db3d ARM: 8772/1: kprobes: Prohibit kprobes on get_user functions 
commit 0d73c3f8e7 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.
