2006-09-20[S390] Missing initialization in common i/o layer.Heiko Carstens
Previous patch that was intended to reduce stack usage within common i/o layer didn't consider implicit memset(..., 0, ...) used with the initializations used before. Add these missing memsets wherever it's not obvious that the concerned memory region is zeroed. This should give the same semantics as before.

2006-09-20[S390] dasd deadlock after state change pending interrupt.Martin Schwidefsky
The dasd_device_from_cdev function is called from interrupt context to get the struct dasd_device associated with a ccw device. The driver_data of the ccw device points to the dasd_devmap structure which contains the pointer to the dasd_device structure. The lock that protects the dasd_devmap structure is acquire with out irqsave. To prevent the deadlock in dasd_device_from_cdev if it is called from interrupt context the dependency to the dasd_devmap structure needs to be removed. Let the driver_data of the ccw device point to the dasd_device structure directly and use the ccw device lock to protect the access. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2006-09-20[S390] zcrypt user space interface.Martin Schwidefsky
The user space interface of the zcrypt device driver implements the old user space interface as defined by the old z90crypt driver. Everything is there, the /dev/z90crypt misc character device, all the lovely ioctls and the /proc file. Even writing to the z90crypt proc file to configure the crypto device still works. It stands to reason to remove the proc write function someday since a much cleaner configuration via the sysfs is now available. The ap bus device drivers register crypto cards to the zcrypt user space interface. The request router of the user space interface picks one of the registered cards based on the predicted latency for the request and calls the driver via a callback found in the zcrypt_ops of the device. The request router only knows which operations the card can do and the minimum / maximum number of bits a request can have.

2006-09-20[S390] zcrypt adjunct processor bus.Martin Schwidefsky
Add a bus for the adjunct processor interface. Up to 64 devices can be connect to the ap bus interface, each device with 16 domains. That makes 1024 message queues. The interface is asynchronous, the answer to a message sent to a queue needs to be received at some later point in time. Unfortunately the interface does not provide interrupts when a message reply is pending. So the ap bus needs to implement some fancy polling, each active queue is polled once per 1/HZ second or continuously if an idle cpus exsists and the poll thread is activ (see poll_thread parameter). The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes, ap_domain and config_time. The ap_domain selects one of the 16 domains to be used for this system. This limits the maximum number of ap devices to 64. The config_time attribute contains the number of seconds between two ap bus scans to find new devices. The ap bus uses the modalias entries of the form "ap:tN" to autoload the ap driver for hardware type N. Currently known types are: 3 - PCICC, 4 - PCICA, 5 - PCIXCC, 6 - CEX2A and 7 - CEX2C.

[PATCH 6/9] s390: qeth driver fixes [3/6] From: Frank Pavlic <fpavlic@de.ibm.com> fixed kernel panic caused by qeth driver: Using a bonding device qeth driver will realloc headroom for every skb coming from the bond device. Once this happens qeth frees the original skb and set the skb pointer to the new realloced skb. Under heavy transmit workload (e.g.UDP streams) through bond network device the qdio output queue might get full. In this case we return with EBUSY from qeth_send_packet. Returning to qeth_hard_start_xmit routine the skb address on the stack still points to the old address, which has been freed before. Returning from qeth_hard_start_xmit with EBUSY results in requeuing the skb. In this case it corrupts the qdisc queue and results in kernel panic.
