Following this email I'm sending 2 patches (clean cherry-picks) that fix
CVE-2016-4794 for vivid and xenial.  Earlier kernels are not impacted by this
issue.

Tejun Heo (2):
  percpu: fix synchronization between chunk->map_extend_work and chunk
    destruction
  percpu: fix synchronization between synchronous map extension and
    chunk destruction
