This patch series is motivated by Shuah's suggestion here: https://lore.kernel.org/kvm/d576d8f7-980f-3bc6-87ad-5a6ae45609b8@xxxxxxxxxxxxxxxxxxx/ Many s390x KVM selftests do not output any information about which tests have been run, so it's hard to say whether a test binary contains a certain sub-test or not. To improve this situation let's add some TAP output via the kselftest.h interface to these tests, so that it easier to understand what has been executed or not.
