Patch enables early intialization of cpu_to_node. apicid_to_node is built by reading the SRAT table, from acpi_numa_init with ACPI_NUMA and k8_scan_nodes with K8_NUMA. x86_cpu_to_apicid is built by parsing the ACPI MADT table, from acpi_boot_init. We combine these two tables and setup cpu_to_node. Early intialization helps the static per_cpu_areas in getting pages from correct node. Change since last release: Do not initialize early init_cpu_to_node for faking node cases. Patch tested on TYAN dual core 4P board with K8 only, ACPI_NUMA. Tested on EM64T NUMA. Also tested with numa=off, numa=fake, and running a kernel compiled with NUMA on a regular EM64 2 way SMP.
