From 237a0989e2902b7d43c4228a36d82f8691fb2118 Mon Sep 17 00:00:00 2001 From: Mike Kravetz Date: Mon, 5 Dec 2005 12:06:42 -0800 Subject: [PATCH] powerpc: numa placement for dynamically added memory This places dynamically added memory within the appropriate numa node. A new routine hot_add_scn_to_nid() replicates most of the memory scanning code in parse_numa_properties().
