    Subject[PATCH v4 0/4] coresight: Do not call smp_processor_id from pre-emptible contexts
    Date
    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. Instead
    use NUMA_NO_NODE to avoid a splat.


    Changes since v3:
    - No function changes. Fix the commit description
    Changes since V2:
    - Use NUMA_NO_NODE instead of numa_node_id() for event->cpu == -1. (Robin Murphy)
