I applied the above on pci/hotplug for v4.10, without the stable
annotation.  If we get reports that would justify stable backports, we
can always request that later.  The ideal thing would be to get those
reports soon enough that we can reference them in the changelog and
add the stable annotations back before these get merged for v4.10.

I'm holding off on this one, pending resolution of the locking
question.
