Subject: [RFC 0/2] perf: add AUX space to ring_buffer

Hi Peter,

I tried to bend my head around the AUX space and this is where I am at
the moment. Not posting the whole itrace/PT bulk yet, to make sure
this part is ok and to save bandwidth.

  perf: add AUX area to ring buffer for raw data streams
