[PATCH v7 1/2] nohz: add tick_nohz_full_add_cpus_to() and _remove_cpus_from() APIs

2015-04-10 Thread Chris Metcalf
The "removes_cpus_from" API is useful, for example, to modify a cpumask to avoid the nohz cores so that interrupts aren't sent to them. Likewise the "add_cpus_to" API is useful to modify a cpumask indicating some special nohz-type functionality so that the nohz cores are automatically added to tha
