Type:void

Parameter:

struct cpuinfo_x86 *	c

cpu = smp_processor_id()

421

apicid = apicid

423

node = numa_cpu_node(cpu)

424

If node == NUMA_NO_NODE Then node = per_cpu(Last level cache ID of each logical CPU , cpu)

432

If fixup_cpu_id Then fixup_cpu_id(c, node)

435

If Not node_online(node) Then

455

ht_nodeid = initial_apicid

457

If __apicid_to_node[] stores the raw mapping between physical apicid and* node and is used to initialize cpu_to_node mapping[ht_nodeid] != NUMA_NO_NODE Then node = __apicid_to_node[] stores the raw mapping between physical apicid and* node and is used to initialize cpu_to_node mapping[ht_nodeid]

460

If Not node_online(node) Then node = To workaround broken NUMA config. Read the comment in* srat_detect_node().
