[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(). Signed-off-by: Mike Kravetz <kravetz@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
