x86 has implemented a set of codes to scan NUMA nodes. These
codes will parse NUMA memory and processor information from
ACPI SRAT table. But except some ACPI specific codes, most
of the scan codes like memory blocks validation, node memory
range updates and some sanity check can be reused by other
