Create a simple macro to always return a pointer to the node_to_cpumask(node)
value. This relies on compiler optimization to remove the extra indirection:
#define node_to_cpumask_ptr(v, node) \
cpumask_t _##v = node_to_cpumask(node), *v = &_##v
For those systems with a large cpumask size, then a true pointer
to the array element can be used:
#define node_to_cpumask_ptr(v, node) \
cpumask_t *v = &(node_to_cpumask_map[node])
A node_to_cpumask_ptr_next() macro is provided to access another
node_to_cpumask value.
The other change is to always include asm-generic/topology.h moving the
ifdef CONFIG_NUMA to this same file.
Note: there are no references to either of these new macros in this patch,
only the definition.
