Andy Lutomirski 0cdd192cf4 kprobes/x86: Don't try to resolve kprobe faults from userspace 
This commit:

    commit 6f6343f53d
    Author: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com>
    Date:   Thu Apr 17 17:17:33 2014 +0900

        kprobes/x86: Call exception handlers directly from do_int3/do_debug

appears to have inadvertently dropped a check that the int3 came
from kernel mode.  Trying to dereference addr when addr is
user-controlled is completely bogus.
