True. I'll reword the above to:

  The ARM CCN PMU driver uses dev_warn() to complain about parameters in
  the user-provided perf_event_attr. This means that under normal
  operation (e.g. a single invocation of the perf tool), a number of
  messages warnings may be logged to dmesg.

... with that, can I take your ack?

Thanks,
Mark.
