[PATCH 4.4 53/74] um: link vmlinux with -no-pie

From: Greg Kroah-Hartman
Date: Mon Jan 29 2018 - 15:12:44 EST


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

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

From: Thomas Meyer <thomas@xxxxxxxx>

commit 883354afbc109c57f925ccc19840055193da0cc0 upstream.

Debian's gcc defaults to pie. The global Makefile already defines the -fno-pie option.
Link UML dynamic kernel image also with -no-pie to fix the build.
