Arnaldo/Adrian:
Latest acme core tree fails to parse an existing data file:
$ perf trace -i perf.data
0x16b8 [0x40]: failed to process type: 1
Failed to process events, error -22
git bisect traced it to:
$ git bisect bad
75562573bab35b129cfd342fc2bcf89da84a6644 is the first bad commit

perf tools: Add support for PERF_SAMPLE_IDENTIFIER
Enable parsing of samples with sample format bit
PERF_SAMPLE_IDENTIFIER.
In addition, if the kernel supports it, prefer it to selecting
PERF_SAMPLE_ID thereby allowing non-matching sample types.

If I revert the patch (and handle the missing __perf_evsel__sample_size
in the tests code to get it to compile) it works -- file is parsed
correctly.
