x86: remove the static 256k node_to_cpumask_map
* Consolidate node_to_cpumask operations and remove the 256k
byte node_to_cpumask_map. This is done by allocating the
node_to_cpumask_map array after the number of possible nodes
(nr_node_ids) is known.
* Debug printouts when CONFIG_DEBUG_PER_CPU_MAPS is active have
been increased. It now shows faults when calling node_to_cpumask()
and node_to_cpumask_ptr().
For inclusion into sched-devel/latest tree.
Based on:
