You really dont need to manipulate any of the system cpu maps. They should
be read-only for most use. When setting up per-cpu resources almost always use
cpu_possible_map/for_each_cpu() to iterate.
cpu_possible_map/for_each_possible_cpu() to iterate.

Never use anything other than cpumask_t to represent bitmap of CPUs.

#include <linux/cpumask.h>

for_each_cpu - Iterate over cpu_possible_map
for_each_possible_cpu - Iterate over cpu_possible_map
for_each_online_cpu - Iterate over cpu_online_map
for_each_present_cpu - Iterate over cpu_present_map
for_each_cpu_mask(x,mask) - Iterate over some random collection of cpu mask.
