[PATCH RESEND] um: vdso: remove unused vdso-syms.lds

[Masahiro Yamada]

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.

The previous post has gone to the moderator
due to too many recipients.
I am resending this.
I hope this is reaching UML maintainers.
