@cmsbuild please test

I want to see the jenkins results before signing off.
I would also like to see a bit more of a description - not a copy of the subject (doesn't improve our documentation).
I tested 83bbe32 on top of CMSSW_7_2_X_2014-11-08-0200 - short matrix tests,, FWLite + DQM comparisons. No diffs in the monitored quantities and none expected. No issues for RECO.

@cmsbuild please test

@nclopezo can you please check why tests are not run on this PR?

For 83bbe32 .
Based on the tests above and on the jenkins results in #6288 (identical PR for 73X) - no diffs and none expected.
