Subject: x86/process: Re-export start_thread()
X-Git-Tag: v4.14.68~51
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cedb8037f0697a8c1b206ca7b02150182adb049b;p=platform%2Fkernel%2Flinux-exynos.git

x86/process: Re-export start_thread()

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")
