Date: Thu, 9 Oct 2008 11:20:27 -0400 From: Neil Horman To: linux-kernel@vger.kernel.org, kexec@lists.infradead.org, vgoyal@redhat.com, hbabu@us.ibm.com Subject: [PATCH] add additional symbols to /sys/kernel/vmcoreinfo data for ppc(64) Cc: nhorman@tuxdriver.com Patch-mainline: not yet 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.
