+Subject: [PATCH] add additional symbols to /sys/kernel/vmcoreinfo data for
+ ppc(64)
+Cc: nhorman@tuxdriver.com
+
+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
