kprobes/x86: Don't try to resolve kprobe faults from userspace
This commit:
commit 6f6343f53d133bae516caf3d254bce37d8774625
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.
