Hi,

This is the 3rd version of bugfix series for kprobes on arm.
This series fixes 4 different issues which I found.

 - Fix to use smp_processor_id() after disabling preemption.
 - Prohibit probing on optimized_callback() for avoiding
   recursive probe.
 - Prohibit kprobes on do_undefinstr() by same reason.
 - Prohibit kprobes on get_user() by same reason.

>From v2, I included another 2 bugfixes (1/4 and 2/4)
which are not merged yet, and added "Cc: stable@vger.kernel.org",
since there are obvious bugs.

Thanks,

---
