The latest RHEL7 kernel: 3.10.0-514.el7.x86_64

Just two weeks ago all tests except static/sched_policy00 would work,
now I have to exclude at least

-x zdtm/static/pthread00 -x zdtm/static/pthread01 -x zdtm/static/maps01
-x zdtm/static/maps00 -x zdtm/transition/maps008 -x zdtm/transition/shmem

Replacing the kernel with a newer version let's those tests pass.
