3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Rian Hunter <[email protected]> commit dc76803e57cc86589c4efcb5362918f9b0c0436f upstream. The consolidation of the start_thread() functions removed the export unintentionally. This breaks binfmt handlers built as a module. Add it back.
