From: Aneesh Kumar K.V aneesh.kumar@linux.ibm.com
commit 7b31f7dadd7074fa70bb14a53bd286ffdfc98b04 upstream.
For both CONFIG_NUMA enabled/disabled use mem_topology_setup() to update max/min_low_pfn.
This also adds min_low_pfn update to CONFIG_NUMA which was initialized to zero before. (mpe: Though MEMORY_START is == 0 for PPC64=y which is all possible NUMA=y systems)
