Subject: [PATCH v3 00/23] perf: Add infrastructure and support for Intel PT

Hi Peter and all,

Here's a new version of PT support patchset, this time including PT and
BTS drivers and a few more tweaks to the core. I still left out some bits
like core dump support for now. Tooling support is not included in this
series so that it's easier to review the kernel bits, I suppose it's best
to send it separately, since it's quite a huge patchset of its own.

Alexander Shishkin (22):
  perf: Add data_{offset,size} to user_page
  perf: Support high-order allocations for AUX space
  perf: Add a capability for AUX_NO_SG pmus to do software double
    buffering
  perf: Add a pmu capability for "exclusive" events
  perf: Redirect output from inherited events to parents
  perf: Add api for pmus to write to AUX space
  perf: Add AUX record
  perf: Support overwrite mode for AUX area
  perf: Add wakeup watermark control to AUX area
  perf: Add itrace_config to the event attribute
  perf: add ITRACE_START record to indicate that tracing has started
  x86: Add Intel Processor Trace (INTEL_PT) cpu feature detection
  x86: perf: Intel PT and LBR/BTS are mutually exclusive
  x86: perf: intel_pt: Intel PT PMU driver
  x86: perf: intel_bts: Add BTS PMU driver
  perf: Add rb_{alloc,free}_kernel api
  perf: Add a helper to copy AUX data in the kernel
  perf: Add a helper for looking up pmus by type
  perf: itrace: Infrastructure for sampling instruction flow traces
  perf: Allocate ring buffers for inherited per-task kernel events
  perf: itrace: Allow itrace sampling for multiple events
  perf: itrace: Allow sampling of inherited events

Peter Zijlstra (1):
  perf: Add AUX area to ring buffer for raw data streams
