Subject: [ppc64] add missing symbols to vmcoreinfo
Message-id: 20081009173238.GB25273@hmsendeavour.rdu.redhat.com
O-Subject: [RHEL5.3 PATCH]: ppc64: add missing symbols to vmcoreinfo
Bugzilla: 465396
RH-Acked-by: Dave Anderson <anderson@redhat.com>

Hey-
	makedumpfile needs certain kernel symbols to operate in certain
filtering modes during kdump operation.  Those symbols are missing from the
ppc64 kernel.  This patch adds them in properly.  Tested successfully by QA
here.

Best
Neil
