[PATCH v2] Export percpu-refcount functions

[PATCH v2] Export percpu-refcount functions

[Matias Bjorling]

ERROR: "percpu_ref_kill_and_confirm" [...] undefined!

Working on a driver that needs them, but other modules might benefit as well.

The second version changes export symbols to GPL per Paul and Tejun's
suggestion.

Andrew, I don't have any percpu changes queued or scheduled for the
next merge window and I think it'd be easier if you can pick up this
one.  The original patch is at

 http://article.gmane.org/gmane.linux.kernel/1578435/raw

Thanks a lot!
