   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.

  15 Regards
  16 Neil
