| 9 | Hey- | |
| 10 | The makdumpdile dump filtering program, in some modes of operation needs | |
| 11 | the node_data and/or contig_page_data symbols to function properly. These | |
| 12 | symbols are missing from the powerpc kernel. This patch adds those symbols in | |
| 13 | properly. Tested successfully by myself and the reporter. | |
