x86: change size of APICIDs from u8 to u16
Change the size of APICIDs from u8 to u16. This partially supports the new x2apic mode that will be present on future processor chips. (Chips actually support 32-bit APICIDs, but that change is more intrusive. Supporting 16-bit is sufficient for now). Signed-off-by: NJack Steiner <steiner@sgi.com> I've included just the partial change from u8 to u16 apicids. The remaining x2apic changes will be in a separate patch. In addition, the fake_node_to_pxm_map[] and fake_apicid_to_node[] tables have been moved from local data to the __initdata section reducing stack pressure when MAX_NUMNODES and MAX_LOCAL_APIC are increased in size.
