Subject[PATCH 3.18 42/56] x86/process: Re-export start_thread()
Date
3.18-stable 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.

Fixes: e634d8fc792c ("x86-64: merge the standard and compat start_thread() functions")
