When facility 11 is available inside the S390x architecture, 2 new
instructions are available: PTF and STSI with function code 15.

Let's check their availability in QEMU/KVM and their coherence
with the CPU topology provided by the QEMU -smp parameter.

To run these tests successfully you will need the Linux and the QEMU
patches:
