[kvm-unit-tests PATCH v3 0/6] 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)

The original series was started by Nina and finished by me.

Changes in v3:
- Remove unnecessary format loop in test_stfle_format_0() - formats are
  already addressed explicitly
- Added patch to use sclp_feat_check directly for DIAG318
- Add no-stfle prefix to improve test log
- Move prefixes to main() to have prefixes in no-stfle checks

Changes in v2:
- Rework sclp_facilities_setup()
- Removed explicit manual padding from struct sclp_facilities
