4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

commit f6c66d73bb8192d357bb5fb8cd5826920f811d8c upstream.

The "Object code reading" test will not create maps for the PTI entry
trampolines unless the machine environment exists to show that the arch is
x86_64.
