[kvm-unit-tests PATCH v2 0/5] s390x: Add test for STFLE interpretive execution (format-2)

[Christoph Schlameuss <schlameuss@linux.ibm.com>]

Test the shadowing of format-2 facility list when running in VSIE.

The tests will skip the format 2 tests
* if running with unpatched kernels or qemu in G1 or G2
* if running on machines prior IBM z16 GA1 (where ASTFLEIE2 is not
  available)
