[PATCH v2 1/2] nohz: add tick_nohz_full_clear_cpus() and _set_cpus() APIs

2015-04-06 Thread cmetcalf
From: Chris Metcalf The "clear" API is useful, for example, to modify a cpumask to avoid the nohz cores so that interrupts aren't sent to them. Likewise the "set" API is useful to modify a cpumask indicating some special nohz-type functionality so that the nohz cores are automatically added to t
