+ * Severity: Notice
+ * Description:
+ * The z/VM IUCV hypervisor console (HVC) device driver requires the
+ * z/VM inter-user communication vehicle (IUCV).
+ * User action:
+ * Set "hvc_iucv=" to zero in the kernel parameter line and reboot Linux.

+ *   @1: hvc_iucv_devices
+ * Description:
+ * The "hvc_iucv=" kernel parameter specifies the number of z/VM IUCV
+ * hypervisor console (HVC) terminal devices.
+ * The parameter value ranges from 0 to 8.
+ * If zero is specified, the z/VM IUCV HVC device driver is disabled
