This patch series adds a some not yet picked selftests to the kvm s390x
selftest suite.

The additional test cases are covering:
* Assert KVM_EXIT_S390_UCONTROL exit on not mapped memory access
* Assert functionality of storage keys in ucontrol VM
* Assert that memory region operations are rejected for ucontrol VMs

Running the test cases requires sys_admin capabilities to start the
ucontrol VM.
This can be achieved by running as root or with a command like:

    sudo setpriv --reuid nobody --inh-caps -all,+sys_admin \
      --ambient-caps -all,+sys_admin --bounding-set -all,+sys_admin \
      ./ucontrol_test

---

The patches in this series have been part of the previous patch series.
The test cases added here do depend on the fixture added in the earlier
patches.
