[RFC v2 0/7] perf: perf: add AUX space to ring_buffer

[Alexander Shishkin <alexander.shishkin@linux.intel.com>]

Hi Peter,

Here's the 2nd go at the AUX area. This covers pretty much what I need
for Intel PT buffer management.

Alexander Shishkin (6):
  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: add api for pmus to write to AUX space
  perf: add AUX record

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