This patchset contains some minor cleanup, some preparatory work and
then the SCLP unit test itself.
The unit test checks the following:
* Correctly ignoring instruction bits that should be ignored
* Privileged instruction check
* Check for addressing exceptions
* Specification exceptions:
- SCCB size less than 8
- SCCB unaligned
- SCCB overlaps prefix or lowcore
- SCCB address higher than 2GB
* Return codes for
- Invalid command
- SCCB too short (but at least 8)
- SCCB page boundary violation
v3 -> v4
* export sclp_setup_int instead of copying it
* add more comments
* rename some more variables to improve readability
* improve the prefix test
* improved the invalid address test
* addressed further comments received during review
v2 -> v3
* generally improved the naming of variables
* added and fixed comments
* renamed test_one_run to test_one_simple
* added some const where needed
* addresed many more small comments received during review
v1 -> v2
* fix many small issues that came up during the first round of reviews
* add comments to each function
* use a static buffer for the SCCP template when used
