    asm-generic: add node_to_cpumask_ptr macro
    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.
