wait_for_completion_interruptible_timeout() returns -ERESTARTSYS if
interrupted so completion_rc needs to be signed.  The current code
probably returns -ETIMEDOUT if we hit this situation, but after this
patch is applied it will return -ERESTARTSYS.

Using the standard debugging mechanisms is better than
subsystem specific ones when the subsystem doesn't use
a specific struct.

Coalesce long formats.

Using the normal logging styles is preferred over
subsystem specific styles when the subsystem does
not take a specific struct.

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

We returned a freed variable on some error paths when the intent was
to return a NULL.  Part of the reason this was missed was that the
code was confusing because it had too many gotos so I removed them
and simplified the flow a bit.

When start_poll is called, and a target was implicitly activated,
we need to implicitly deactivate it.
On the other hand, when the target was activated by the user,
we should not deactivate it.
