Found another locking issue: the code which verifies we don't export over
an existing symbol needs to be atomic wrt. adding us to the list.

This will be in tomorrow's linux-next.

And load_module is down to 259 lines.  The label chain at the end is no
shorter tho :(  I'll leave those cleanups until next merge window.
