Hi Peter,

This is an RFC, I'm not sending the tooling bits in this series,
although they can be found here [1].

This series introduces AUX data sampling for perf events, which in
case of our instruction/branch tracing PMUs like Intel PT, BTS, CS
ETM means execution flow history leading up to a perf event's
overflow.

The bulk of code is in 4/6, which adds attribute fields, creates
kernel events to generate the AUX data, takes samples and takes care
of all the tricky. 1/6 and 6/6 may also be considered separately from
this series. In particular, I suspect that 6/6 applies today to the
architectures that deliver PMIs as IRQs. Mathieu?

Alexander Shishkin (6):
  perf: Move mlock accounting to ring buffer allocation
  perf: Add api to (de-)allocate AUX buffers for kernel counters
  perf: Add a helper for looking up pmus by type
  perf: Add infrastructure for using AUX data in perf samples
  perf: Disable PMU around address filter adjustment
  perf: Disable IRQs in address filter sync path
