Prototype for __symbol_get_gpl() was introduced in the initial git
commit 1da177e4c3f4 ("Linux-2.6.12-rc2"), but was not used after that.
In commit 9011e49d54dc ("modules: only allow symbol_get of
EXPORT_SYMBOL_GPL modules") Christoph Hellwig switched __symbol_get()
to process GPL symbols only, most likely this is what
__symbol_get_gpl() was designed to do.
We might either define __symbol_get_gpl() as __symbol_get() or remove
it completely as suggested by Mauro Carvalho Chehab.
