-        help
-          There are two drivers for MFM/RLL/IDE hard disks. Most people use
-          the newer enhanced driver, but this old one is still around for two
-          reasons. Some older systems have strange timing problems and seem to
-          work only with the old driver (which itself does not work with some
-          newer systems). The other reason is that the old driver is smaller,
-          since it lacks the enhanced functionality of the new one. This makes
-          it a good choice for systems with very tight memory restrictions, or
-          for systems with only older MFM/RLL/ESDI drives. Choosing the old
-          driver can save 13 KB or so of kernel memory.
-
-          If you want to use this driver together with the new one you have
-          to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
-          driver from probing the primary interface.
-
-          If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver

+ * Slots are uniquely identified by a @pci_bus, @slot_nr, @name tuple.
+ *
+ * Placeholder slots:
+ * In most cases, @pci_bus, @slot_nr will be sufficient to uniquely identify
+ * a slot. There is one notable exception - pSeries (rpaphp), where the
+ * @slot_nr cannot be determined until a device is actually inserted into
+ * the slot. In this scenario, the caller may pass -1 for @slot_nr.
+ *
+ * The following semantics are imposed when the caller passes @slot_nr ==
+ * -1. First, the check for existing %struct pci_slot is skipped, as the
+ * caller may know about several unpopulated slots on a given %struct
+ * pci_bus, and each slot would have a @slot_nr of -1.  Uniqueness for
+ * these slots is then determined by the @name parameter. We expect
+ * kobject_init_and_add() to warn us if the caller attempts to create
+ * multiple slots with the same name. The other change in semantics is
+ * user-visible, which is the 'address' parameter presented in sysfs will
+ * consist solely of a dddd:bb tuple, where dddd is the PCI domain of the
+ * %struct pci_bus and bb is the bus number. In other words, the devfn of

-         * during reconfiguration of their Guest LAN (only in HIPERS mode,
-         * QDIO mode is asynchronous -- cc=2 and busy bit there will take
-         * the queues down immediately; and not being under VM we have a
-         * problem on cc=2 and busy bit set right away).
-         *
-         * Therefore qdio_siga_output will try for a short time constantly,
-         * if such a condition occurs. If it doesn't change, it will
-         * increase the busy_siga_counter and save the timestamp, and
-         * schedule the queue for later processing (via mark_q, using the
-         * queue tasklet). __qdio_outbound_processing will check out the
-         * counter. If non-zero, it will call qdio_kick_outbound_q as often
-         * as the value of the counter. This will attempt further SIGA
-         * instructions. For each successful SIGA, the counter is
-         * decreased, for failing SIGAs the counter remains the same, after
-         * all.
-         * After some time of no movement, qdio_kick_outbound_q will
-         * finally fail and reflect corresponding error codes to call
-         * the upper layer module and have it take the queues down.
-         *
-         * Note that this is a change from the original HiperSockets design
-         * (saying cc=2 and busy bit means take the queues down), but in
-         * these days Guest LAN didn't exist... excessive cc=2 with busy bit
-         * conditions will still take the queues down, but the threshold is
-         * higher due to the Guest LAN environment.
