[PATCH v2 0/4] KVM: s390: selftests: Provide TAP output in tests

[Thomas Huth <thuth@redhat.com>]

This patch series is motivated by Shuah's suggestion here:

 https://lore.kernel.org/kvm/d576d8f7-980f-3bc6-87ad-5a6ae45609b8@linuxfoundation.org/

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.

v2:
 - Reworked the extension checking in the first patch
 - Make sure to always print the TAP 13 header in the second patch
 - Reworked the SKIP printing in the third patch

  KVM: s390: selftests: Use TAP interface in the memop test
  KVM: s390: selftests: Use TAP interface in the sync_regs test
  KVM: s390: selftests: Use TAP interface in the tprot test
  KVM: s390: selftests: Use TAP interface in the reset test
