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)
