Does this preserve the correct fake apicid_to_node mapping for the
emulated case such as numa=fake=32?
+void __init update_apicid_to_node(void)
+{
+ /*
+ * let modify apicid_to_node array when boot_cpu_id !=0
+ * apicid_to_node[0] != NUMA_NODE
+ */
+
+ int i;
+
+ /* there is no apic id offset */
+ if (!boot_cpu_id)
+ return;
+
+ /* check if it is already updated */
+ if (apicid_to_node[0] == NUMA_NO_NODE)
+ return;
boot_cpu_id (bsp apic id ) is 0 under fake numa case?
or need to add some exit for fake numa mode.
