Hi Avi, Hi Marcelo, I think I've integrated all feedback from last round. The race between KVM_S390_ENABLE_UCONTROL and creation of vcpus has been resolved by adding a parameter to KVM_CREATE_VM. The default KVM_VM_REGULAR (==0) is backward compatible to KVM_CREATE_VM without parameters, and KVM_VM_S390_UCONTROL enables user controlled virtual machines for CECSIM. The extra ioctl is gone. The page table walk in the storage key patch has moved to arch/s390/mm, and I think this patch should go with the rest of this series via your tree after Martin reviewed it. so long, Carsten -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
