[PATCH 32/32] nohz/cpuset: Disable under some configs

[Frederic Weisbecker]

This shows the various things that are not yet handled by
the nohz cpusets: perf events, irq work, irq time accounting.

But there are further things that have yet to be handled:
sched clock tick, runqueue clock, sched_class::task_tick(),
rq clock, cpu load, complete handling of cputimes, ...
