From 2a4814df545a0645aff6fc04e5106877cc576945 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 8 Dec 2011 10:22:08 -0800 Subject: [PATCH] sparc: Use HAVE_MEMBLOCK_NODE_MAP sparc doesn't access early_node_map[] directly and enabling HAVE_MEMBLOCK_NODE_MAP is trivial - replacing add_active_range() calls with memblock_set_node() and selecting HAVE_MEMBLOCK_NODE_MAP is enough. -v2: Use select in Kconfig instead as suggested by Sam Ravnborg.
