From b5722a457b6e5eabd97a7f39c6c2b8e9a623ab15 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 3 Jul 2018 10:50:13 +0900 Subject: [PATCH] x86/build/vdso: Remove unused vdso-syms.lds This file contains symbol values, and was originally linked into vmlinux, but I have no idea what it was actually used for. Since the following commit: 827880ec260b ("x86/um: thin archives build fix") it is not even linked. Now it is completely orphan, and no problem has been reported. It is a proof that this file was not needed in the first place.
