[PATCH -tip v8 06/26] [BUGFIX] x86: Prohibit probing on native_set_debugreg/load_idt

2014-03-05 Thread Masami Hiramatsu
Prohibit probing on native_set_debugreg and native_load_idt. Since the kprobes uses do_debug for single stepping, functions called from do_debug before notify_die must not be probed. And also native_load_idt is called from paranoid_exit when returning int3, this also must not be probed. Signed-off
