We do two things, both of which are purely to simplify and clarify the implementation: 1. Simplify the CPU online callback so it is more obvious that the purpose there is to set a single CPU mask bit for the first CPU which comes online. Using cpumask_weight for this reads more obvious than the trick with cpumask_and_any. 2. Modify the event init so that events can be created only on a single CPU. This removes looking at the requested CPU thread siblings, and only allows creating on the current active CPU.
