Enable perf tool to exploit POWER 24x7 hardware counters
Parts of the project:
a) Some patches upstream and done
b) Reset targets on remaining features still to be done (jit support, symbol names)
== Comment: #16 - Breno Henrique Leitao <email address hidden> - 2015-02-24 08:06:45 ==
Initial patches already accepted by Canonical on 117275. Patchset posted to community, waiting on
review. (I had posted a version of the patchset in Dec after fixing minor comments. Waiting to hear back from community )

Never mind.
'git describe' seems to think they are in 3.19-rcX but they are
not in 3.19.
$ git describe fd979c0
v3.19-rc2-
$ git describe aaea361
v3.19-rc4-
They were merged on Feb 2, so they should be in 4.0
