Get rid of the "travis: Update travis-ci with new kernel releases" in the git log

[rsglobal]

I was wondering if we could put all the regression testing against new kernel into the separate pull request
or into the separate branch?
Here is my vision how it can be actually implemented:
$ git checkout master-travis
$ git reset --hard master
$ <do_update .travis.yml>
$ git commit -a --no-edit
$ git diff master master-travis --exit-code || git push --force
