C) KVM/s390 reorganization (patches 12-22):So I picked 12-21 for kvms390/next and left 22 for later.
Prepare s390 for a second KVM module. Move existing s390 KVM code into
dedicated s390 and gmap subdirectories to make room for a second KVM
implementation. Refactor gmap to better integrate with the second KVM
implementation. GMAP hides a few features only required when managing s390
guests: Storage keys, CMMA, and prefix handling. Those are guarded behind an
#if KVM_S390_MANAGES_S390_GUEST. Only features which implementation would
break kvm-arm64 code are guarded. I leave the non-breaking stuff (like
shadow-gmaps or ucontrol) for the LTO.
