x86_32 has been managing node_to_cpumask_map explicitly from
map_cpu_to_node() and friends in a rather ugly way. With
previous changes, it's now possible to share the code with
64bit.
* When CONFIG_NUMA_EMU is disabled, numa_add/remove_cpu() are
implemented in numa.c and shared by 32 and 64bit. CONFIG_NUMA_EMU
versions still live in numa_64.c.
NUMA_EMU's dependency on 64bit is planned to be removed and the
above should go away together.
* identify_cpu() now calls numa_add_cpu() for 32bit too. This
makes the explicit mask management from map_cpu_to_node() unnecessary.
* The whole x86_32 specific map_cpu_to_node() chunk is no longer
necessary. Dropped.
