Subject: [PATCH 23/33] modpost white list pattern adjustment

From: Jan Beulich <jbeulich@...ell.com>

gcc puts data into .data.rel or .data.rel.* on some architectures (e.g.
ia64) or under certain conditions, so whatever is legal relative to
.data should also be legal for those other sections. Fixes a few
modpost warnings on ia64.
