[PATCH v3 0/4] coresight: Do not call smp_processor_id from preemptible contexts

[Suzuki K Poulose]

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)

    preemptible
  coresight: tmc-etf: Do not call smp_processor_id from preemptible
  coresight: etb10: Do not call smp_processor_id from preemptible
