We have a few places where we call smp_processor_id() from preemptible
contexts during the perf buffer handling. We do this to figure out the
numa node for the allocation in case the event is not CPU bound. Use
numa_node_id() instead in such cases to avoid a splat.
Changes since V2:
- Use NUMA_NO_NODE instead of numa_node_id() for event->cpu == -1. (Robin
Murphy)
