Subject: [PATCH 1/2] cpu_hotplug: Remove __cpuinitdata declaration of __apicid_to_node[].

__apicid_to_node[] will be used by acpi_unmap_lsapic() when we do
node hotplug. So it is no longer an init data. Do not declare
__apicid_to_node[] as a __cpuinitdata, otherwise it will cause
section mismatch warning when compiling.
