- * CPUMASK_ALLOC kmalloc's a structure that is a composite of many cpumask_t
- * variables, and CPUMASK_PTR provides pointers to each field.
- *
- * The structure should be defined something like this:
- * struct my_cpumasks {
- * cpumask_t mask1;
- * cpumask_t mask2;
- * };
- *
- * Usage is then:
- * CPUMASK_ALLOC(my_cpumasks);
- * CPUMASK_PTR(mask1, my_cpumasks);
- * CPUMASK_PTR(mask2, my_cpumasks);
- *
- * --- DO NOT reference cpumask_t pointers until this check ---
- * if (my_cpumasks == NULL)
- * "kmalloc failed"...
- *
- * References are now pointers to the cpumask_t variables (*mask1, ...)

- *if NR_CPUS > BITS_PER_LONG
- * CPUMASK_ALLOC(m) Declares and allocates struct m *m =
