Paolo, Radim,
the first pull request for 4.20 (or 5?) for KVM on s390. Mostly the
vfio-ap support (KVM virtualization for crypto cards). This touches
also base s390 - and depending on the kind of change I also expect
future changes for vfio-ap via Martins tree.
In case there will be addon changes via Martins tree I have created the
topic branch "apv11" and merged that. If necessary, Martin can pull that
topic branch as well. As of today there is no conflict, so right now
this goes via the KVM tree.
Please pull
