x86: Use HAVE_MEMBLOCK_NODE_MAP
From 5732e1247898d67cbf837585150fe9f68974671d Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Thu, 14 Jul 2011 11:22:16 +0200 Convert x86 to HAVE_MEMBLOCK_NODE_MAP. The only difference in memory handling is that allocations can't no longer cross node boundaries whether they're node affine or not, which shouldn't matter at all. This conversion will enable further simplification of boot memory handling. -v2: Fix build failure on !NUMA configurations discovered by hpa.
