Comment 7 for bug 1837525

Now some of the odd things:

Old tests that passed, that have disappeared (50 tests): (Eeek!)

So, these tests do exist, are compiled, but then not executed, as if these are no longer supported to be executed on -march=z13?
Or do our QEMU KVM virtual machines lack some settings on the LPAR in HMC or on the QEMU VM cmdline to execute them?
