kvm_s390_mem_op() can fail in two ways: when !cap_mem_op, it returns -ENOSYS, and when kvm_vcpu_ioctl() fails, it returns -errno set by ioctl(). Its caller s390_cpu_virt_mem_rw() recovers from both failures. kvm_s390_mem_op() prints "KVM_S390_MEM_OP failed" with error_printf() in the latter failure mode. Since this is obviously a warning, use warn_report(). Perhaps the reporting should be left to the caller. It could warn on failure other than -ENOSYS.
