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


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.

Suzuki K Poulose (4):
  coresight: tmc-etr: Do not call smp_processor_id() from preemptible
  coresight: tmc-etr: alloc_perf_buf: Do not call smp_processor_id from
    preemptible
  coresight: tmc-etf: Do not call smp_processor_id from preemptible
  coresight: etb10: Do not call smp_processor_id from preemptible
