[kvm-unit-tests GIT PULL 00/18] s390x: new edat, diag258 and STFLE tests; fixes for genprotimg >= 2.36.0; cleanups for snippets and makefiles

[Nico Boehr <nrb@linux.ibm.com>]

Hi Paolo and/or Thomas,

Changes in this pull request:
- cpacf query function were reworked in the kernel, that fix was
  cherry-picked by Nina. This fixes issues with possible incorrect
  instruction format
- Claudio extended the edat test for a special case with a 2G page at
  the end of memory to ensure the correct addressing exception happens.
- I added a test for diag258 where we had some issues with
  virtual-physical address confusion.
- Nina took the time to add library functions that help exiting from a
  snippet s390x.
- Nina contributed a test for STFLE interpretive execution. Thank you!
- Marc did a lot of magic fixing issues in our Makefiles. This fixes
  several issues with out-of-tree-builds. We now also build out-of-tree
  in our downstream CI to avoid unpleasant surprises for maintainers :)
  Marc, thanks for contributing your Makefile knowledge and for turning my
  complaints into something productive
- Janosch also invested some time to clean up snippets and Makefiles,
  which made the code a lot nicer, thanks for that as well!
- we have a compatibility issue with genprotimg
  versions >= 2.36.0. Thanks Marc to fixing that. You should upgrade
  kvm-unit-tests if you use genprotimg >= 2.36.0!

Note that there are two checkpatch errors:
> ERROR: space prohibited before that ':' (ctx:WxW)
I would suggest to ignore them, the code really looks ugly otherwise.

Thanks
Nico
