From: Tejun Heo Date: Thu, 8 Dec 2011 18:22:08 +0000 (-0800) Subject: powerpc: Use HAVE_MEMBLOCK_NODE_MAP X-Git-Tag: MMI-PSA29.97-13-9~17768^2^2~8 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d7cfe18ec2eb2d0480a9b29465af66b61291202;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git powerpc: Use HAVE_MEMBLOCK_NODE_MAP powerpc 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.
