---
Changes in V7:
-- Remove some node initialization/allocation from boot setup
to later in runtime to try to limit memory needs early on
-- Add some needed node initialization to runtime code that maps
CPUs based on VPHN associativity
-- Add error checks and alternate recovery for compile flag
CONFIG_MEMORY_HOTPLUG
-- Add alternate node selection recovery for !CONFIG_MEMORY_HOTPLUG
-- Add initialization for systems that start using nodes before new
CPU brought online.
-- Make function find_cpu_nid() externally visible/usable so that
it may be used from hotplug-cpu.c
