The YYLTYPE_IS_TRIVIAL is defined in the Build file, but unlike
pmu-bison.c, gcc complained about it for parse-events-bison.c:

    CC       util/parse-events-bison.o
  In file included from util/parse-events.y:16:
  util/parse-events-bison.h:101:1: error: "YYLTYPE_IS_TRIVIAL" redefined
  <command-line>: error: this is the location of the previous definition
  make[3]: *** [util/parse-events-bison.o] Error 1

Comments from Jiri Olsa:

"Reason is the parse error handling that was added just recently: it
adds YYLTYPE type (which is not present in pmu-bison.h), so
YYLTYPE_IS_TRIVIAL gets redefined, which is ok in F20 that handle the
error via '-w' option, but it's not ok for RHEL6 where the '-w' does not
work for this kind of error."

This patch supports the addition to the kernel of AUX area buffers that
can be mmapped separately from the perf-events buffer.

The AUX buffer can be configured to contain hardware-produced trace
information. The first implementation will support Intel BTS and Intel
PT.

One auxtrace buffer is mmapped per perf-events buffer.  If the requested
auxtrace buffer size is zero, which it will be until further support is
added, then no auxtrace mmapping is attempted.

In short, Fedora compresses kernel modules now (since version 21) with
lzma compression.

Adding lzma decompress support into the dso.c:compressions array
introduced by Namhyung earlier.

Adding 'perf data convert' to convert perf data file into different
format. This patch adds support for CTF format conversion.

To convert perf.data into CTF run:
  $ perf data convert --to-ctf=./ctf-data/
  [ perf data convert: Converted 'perf.data' into CTF data './ctf-data/' ]
  [ perf data convert: Converted and wrote 11.268 MB (100230 samples) ]

The command will create CTF metadata out of perf.data file (or one
specified via -i option) and then convert all sample events into single
CTF stream.

Each sample_type bit is translated into separated CTF event field apart
from following exceptions:

  PERF_SAMPLE_RAW          - added in next patch
  PERF_SAMPLE_READ         - TODO
  PERF_SAMPLE_CALLCHAIN    - TODO
  PERF_SAMPLE_BRANCH_STACK - TODO
  PERF_SAMPLE_REGS_USER    - TODO
  PERF_SAMPLE_STACK_USER   - TODO

  $ perf --debug=data-convert=2 data convert ...

The converted CTF data could be analyzed by CTF tools, like babletrace
or tracecompass [1].

The following members to the ctf-environment were decided to be added to
distinguish and specify perf CTF data:

  - domain

    It says "kernel" because it contains a kernel trace (not to be
    confused with a user space like lttng-ust does)

  - tracer_name

    It says perf. This can be used to distinguish between lttng and perf
    CTF based trace.

  - version

    The kernel version from stream. In addition to release, this is what
    it looks like on a Debian kernel:

      release = "3.14-1-amd64";
      version = "3.14.0";
