Hey Vivek, as promised, a corrected patch
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
