    Subject[PATCH 4.14 115/165] x86/process: Re-export start_thread()
    Date
    4.14-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")
