Subject: [PATCH] add additional symbols to /sys/kernel/vmcoreinfo data for ppc(64)
Date: Thursday, October 9, 2008 - 11:20 am

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
