4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rian Hunter <r...@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.
Fixes: e634d8fc792c ("x86-64: merge the standard and compat start_thread()
functions")
