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_possible_cpu() to iterate. +cpu_possible_map/for_each_cpu() to iterate. Never use anything other than cpumask_t to represent bitmap of CPUs. #include -for_each_possible_cpu - Iterate over cpu_possible_map +for_each_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.
