Merge tag 'kvm-s390-next-6.6-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD
- PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
- Guest debug fixes (Ilya)
