[GIT PULL 0/8] perf/pt -> Intel PT/BTS

Hi Ingo,

Please consider pulling, there are several other patches after this,
but I think that this may be acceptable to showcase the capabilities already
present, look at the output of 'perf script' and callchains for userspace
without using any extra debugging info (no need for DWARF, CFI, nothing),
really cool capabilities... :-)

Adrian wrote some docs and I tested it both on a Ivy Bridge machine
where there is only BTS and on a Broadwell machine with the whole shebang,
adding the output of the commands to the csets, to further showcase what is
there already.

This is on top of my last perf-core-for-mingo tag.

Up to you, please let us know what you think and we'll continue working
on having this in an acceptable form for merging,

Regards,

- Arnaldo

P.S. Kudos for Adrian for the patience with this process, way more is needed to
polish this, but the promise is there, cool stuff indeed! :-)
