Hi,

I wanted to pick this, but unfortunately, there are some problems with
it, as spotted by checkpatch (sadly, I did not see this earlier, and
softfreeze is upon us...)

- Licensing information: new files (e.g. cpacf.h) must use an SPDX
  identifier instead of licence boilerplate text - this needs to be fixed
- some files are using tabs instead of spaces in some places
- there are also some other moans (less important), but you may want to
  look at them anyway (the long lines are not really a problem)
