Subject: [PATCH] zipl/boot: stage3.lds.S: put notes section explicitly at the
 end
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

...otherwise `.note.gnu.build-id` will be put at 0x0 (location for s390x
lowcore) if the linker option `--build-id` is used (which is the default
if gcc is used for linking).
