Subject: [PATCH] add additional symbols to /sys/kernel/vmcoreinfo data for

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
|
