3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Rian Hunter rian@alum.mit.edu
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.
