Well yes, this interface of explicitly marking a task and cpu as
task_no_hz is kinda restrictive and useless.

When I run 4 cpu-bound tasks on a quad-core I shouldn't have to do
anything to benefit from this.

I don't see why having this cpumask is restricting you in any way,
user-space tasks don't migrate around, that all happens in kernel space.

Also, I'm not quite happy with the pure userspace restriction, but at
least I see why you did that event though you didn't mention that.
