From 6757eca348fbbdd4ab1020e565f325cd6a6b2698 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Wed, 10 Mar 2010 22:48:34 +0000 Subject: [PATCH] sysfs: Initialised pci bus legacy_mem field before use PPC64 is failing to boot the latest mmotm due to an uninitialised pointer in pci_create_legacy_files(). The surprise is that machines boot at all and it would appear to affect current mainline as well. This patch fixes the problem.
