Paolo, Radim,
here are the s390 updates for KVM for 5.1. The largest change is the
introduction of the GIB, which stores interruptions for guests that
have no running vcpu.
The "s390/cio: add function chsc_sgib()" patch has been reviewed by
our s390 IO maintainer.
The rest is a bit of cleanup and a preparation for processor
subfunction cpu model management usage. Some of our instructions
indicate, which functions they provide, like different crypto
algorithms that are added with new machines.
The following changes since commit bfeffd155283772bbe78c6a05dec7c0128ee500c:
