Subject: [PATCH 0/7] Split Coresight decode by aux records

Hi All,

Since my previous RFC, I've fixed --per-thread mode and solved
most of the open questions. I've also changed --dump-raw-trace
to use the same code path so it's also working now.

I think the only open questions are:
  * General approach
  * If aux records need to be saved, or if they can be pulled
    from elsewhere.

I've also tested perf inject which is now working with troublesome
files.

Thanks
James

  perf cs-etm: Use existing decode code path for --dump-raw-trace
  perf cs-etm: Suppress printing when resetting decoder
