acpi: fix potential call to a freed memory section.
Strip __cpuinit[data] from Node <-> PXM routines and supporting data structures. Also make pxm_to_node_map and node_to_pxm_map local to the numa acpi module. This fixes a bug triggered by the following conditions: - boot on a machine with a SLIT table defined - kernel is configured w/ CONFIG_HOTPLUG_CPU=n - cat /sys/devices/system/node/node*/distance This will cause an oops by calling into a freed memory section. In particular, on x86_64, __node_distance calls node_to_pxm().
