2005-09-05[PATCH] s390: deadlock in dasd_devmapHorst Hummel
Reintroduce a read-only copy of the devmap features in the device struct. This is necessary to solve a deadlock on the dasd_devmap_lock which is acquired by dasd_get_features called from the dasd tasklet. The current implementation of devmap doesn't allow to call any devmap function from interrupt or softirq context.

2005-09-05[PATCH] s390: machine check handler bugsMartin Schwidefsky
The new machine check handler still has a few bugs. 1) The system entry time has to be stored in the machine check handler, 2) the machine check return psw may not be stored at the usual place because it might overwrite the return psw of the interrupted context, 3) the return address for the call to s390_handle_mcck in the i/o interrupt handler is not correct, 4) the system call cleanup has to take the different save area of the machine check handler into account, 5) the machine check handler may not call UPDATE_VTIME before CREATE_STACK_FRAME, and 6) the io leave path needs a critical section cleanup to make sure that the TIF_MCCK_PENDING bit is really checked before switching back to user space.

2005-09-05[PATCH] ppc32: Added support for the Book-E style Watchdog TimerKumar Gala
PowerPC 40x and Book-E processors support a watchdog timer at the processor core level. The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.

2005-08-31[PATCH] iseries_veth: Be consistent about driver name, increment versionMichael Ellerman
The iseries_veth driver tells sysfs that it's called 'iseries_veth', but if you ask it via ethtool it thinks it's called 'veth'. I think this comes from 2.4 when the driver was called 'veth', but it's definitely called 'iseries_veth' now, so fix it. To make sure we don't do it again define DRV_NAME and use it everywhere. While we're at it, change the version number to 2.0, to reflect the changes made in this patch series.

2005-08-31[PATCH] iseries_veth: Fix bogus counting of TX errorsMichael Ellerman
There's a number of problems with the way iseries_veth counts TX errors. Firstly it counts conditions which aren't really errors as TX errors. This includes if we don't have a connection struct for the other LPAR, or if the other LPAR is currently down (or just doesn't want to talk to us). Neither of these should count as TX errors. Secondly, it counts one TX error for each LPAR that fails to accept the packet. This can lead to TX error counts higher than the total number of packets sent through the interface. This is confusing for users. This patch fixes that behaviour. The non-error conditions are no longer counted, and we introduce a new and I think saner meaning to the TX counts. If a packet is successfully transmitted to any LPAR then it is transmitted and tx_packets is incremented by 1. If there is an error transmitting a packet to any LPAR then that is counted as one error, ie. tx_errors is incremented by 1.

2005-08-31[PATCH] iseries_veth: Simplify full-queue handlingMichael Ellerman
The iseries_veth driver often has multiple netdevices sending packets over a single connection to another LPAR. If the bandwidth to the other LPAR is exceeded, all the netdevices must have their queues stopped. The current code achieves this by queueing one incoming skb on the per-netdevice port structure. When the connection is able to send more packets we iterate through the port structs and flush any packet that is queued, as well as restarting the associated netdevice's queue. This arrangement makes less sense now that we have per-connection TX timers, rather than the per-netdevice generic TX timer. The new code simply detects when one of the connections is full, and stops the queue of all associated netdevices. Then when a packet is acked on that connection (ie. there is space again) all the queues are woken up.

2005-08-31[PATCH] iseries_veth: Add a per-connection ack timerMichael Ellerman
Currently the iseries_veth driver contravenes the specification in Documentation/networking/driver.txt, in that if packets are not acked by the other LPAR they will sit around forever. This patch adds a per-connection timer which fires if we've had no acks for five seconds. This is superior to the generic TX timer because it catches the case of a small number of packets being sent and never acked. This fixes a bug we were seeing on real systems, where some IPv6 neighbour discovery packets would not be acked and then prevent the module from being removed, due to skbs lying around.

2005-08-31[PATCH] iseries_veth: Use kobjects to track lifecycle of connection structsMichael Ellerman
The iseries_veth driver can attach to multiple vlans, which correspond to multiple net devices. However there is only 1 connection between each LPAR, so the connection structure may be shared by multiple net devices. This makes module removal messy, because we can't deallocate the connections until we know there are no net devices still using them. The solution is to use ref counts on the connections, so we can delete them (actually stop) as soon as the ref count hits zero. This patch fixes (part of) a bug we were seeing with IPv6 sending probes to a dead LPAR, which would then hang us forever due to leftover skbs.

2005-08-31[PATCH] iseries_veth: Make init_connection() & destroy_connection() symmetricalMichael Ellerman
This patch makes veth_init_connection() and veth_destroy_connection() symmetrical in that they allocate/deallocate the same data. Currently if there's an error while initialising connections (ie. ENOMEM) we call veth_module_cleanup(), however this will oops because we call driver_unregister() before we've called driver_register(). I've never seen this actually happen though. So instead we explicitly call veth_destroy_connection() for each connection, any that have been set up will be deallocated. We also fix a potential leak if vio_register_driver() fails.

2005-08-31[PATCH] iseries_veth: Only call dma_unmap_single() if dma_map_single() succeededMichael Ellerman
The iseries_veth driver unconditionally calls dma_unmap_single() even when the corresponding dma_map_single() may have failed. Rework the code a bit to keep the return value from dma_unmap_single() around, and then check if it's a dma_mapping_error() before we do the dma_unmap_single().
