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.
