x86: change NR_CPUS arrays in numa_64 fixup
Change the following static arrays sized by NR_CPUS to
per_cpu data variables:
char cpu_to_node_map[NR_CPUS];
fixup:
- Split cpu_to_node function into "early" and "late" versions
so that x86_cpu_to_node_map_early_ptr is not EXPORT'ed and
the cpu_to_node inline function is more streamlined.
- This also involves setting up the percpu maps as early as possible.
- Fix X86_32 NUMA build errors that previous version of this
patch caused.
V2->V3:
- add early_cpu_to_node function to keep cpu_to_node efficient
- move and rename smp_set_apicids() to setup_percpu_maps()
- call setup_percpu_maps() as early as possible
V1->V2:
- Removed extraneous casts
- Fix !NUMA builds with '#ifdef CONFIG_NUMA"
