Subject: [PATCH] x86-64, NUMA: Prepare numa_emulation() for moving NUMA
 emulation into a separate file

Update numa_emulation() such that, it

- takes @numa_meminfo and @numa_dist_cnt instead of directly
  referencing the global variables.

- copies the distance table by iterating each distance with
  node_distance() instead of memcpy'ing the distance table.

- tests emu_cmdline to determine whether emulation is requested and
  fills emu_nid_to_phys[] with identity mapping if emulation is not
  used.  This allows the caller to call numa_emulation()
  unconditionally and makes return value unncessary.

- defines dummy version if CONFIG_NUMA_EMU is disabled.

This patch doesn't introduce any behavior change.
