[PATCH v2 0/2] s390x: improve subchannel error handling (vfio)

This is a followup on the first version (which I had sent out in May,
and which kind of fell through the cracks.) While the first patch
is mostly unchanged, I added a second patch to address some possible
problems with the generated unit exceptions; non-vfio subchannels
are not affected by this.

As before, this works on the good path, and I have not managed to
actually get my system to exercise the error path :(

- add comments regarding -ENODEV/-EACCES handling
- add second patch

Cornelia Huck (2):
  vfio-ccw: forward halt/clear errors
  css: fix actl handling for unit exceptions
