Hey-
The makdumpdile dump filtering program, in some modes of operation needs
the node_data and/or contig_page_data symbols to function properly. These
symbols are missing from the powerpc kernel. This patch adds those symbols in
properly. Tested successfully by myself and the reporter.
Regards
Neil
