Why do we have PF_VCPU and CONTEXT_GUEST? What's the difference between them (other than the fact that one is per-task and one is per-cpu)? It would be a bit easier to understand if there were fewer of these things. If the issue is that remote sampling would otherwise have a race that could account guest time to the wrong task, then maybe PF_VCPU makes sense.
