This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_9_2_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar

[alberto-sanchez]

@davidlange6 can this be merged?

[davidlange6]

hi @alberto-sanchez - is this one tested in one of the GEN relvals of 9_2_1?

[perrozzi]

this is the 71x backport and it has been tested heavily
