  * Fixup PERF_SAMPLE_TRANSACTION handling in sample synthesizing and
    'perf test', from Adrian Hunter.

  * Set up output options for in-stream attributes, from Adrian Hunter.

  * Fix 32-bit cross build, from Adrian Hunter.

  * Fix libunwind build and feature detection for 32-bit build, from Adrian Hunter.

  * Always use perf_evsel__set_sample_bit to set sample_type, from Adrian Hunter.
    perf evlist: Add a debug print if event buffer mmap fails

  * Add missing data.h into LIB_H headers, fix from Jiri Olsa.
