[PATCH v2 7/7]powerpc/powernv: nest pmu cpumask and cpu hotplug support

2015-06-10 Thread Madhavan Srinivasan
Adds cpumask attribute to be used by each nest pmu since nest units are per-chip. Only one cpu (first online cpu) from each node/chip is designated to read counters. On cpu hotplug, dying cpu is checked to see whether it is one of the designated cpus, if yes, next online cpu from the same node/chi
