I'm seeing a build failure on ubuntu-trusty master-next on arm64 that
I've bisected to this change:

commit c3208d7fd18ad731a32de34b4423291ff395ad66
Author: Matthew Dempsky <mdempsky at chromium.org>
Date:   Fri Jun 6 14:36:42 2014 -0700

    ptrace: fix fork event messages across pid namespaces

I'm not sure if this impacts upstream 3.13.11.z or not - is there a
git tree I could use to verify?
