[PATCH 1/2] x86/build/vdso: remove unused vdso-syms.lds
From: Masahiro Yamada
Date: Mon Jul 02 2018 - 21:53:02 EST
This file contains symbol values, and was originally linked into
vmlinux, but I have no idea what it was actually used for.
Since 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.
