2007-10-12Driver core: change add_uevent_var to use a structKay Sievers
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-12[S390] 3215: Handle special console device.Cornelia Huck
The early console device is special as it already has all needed data set and raw3215[0] allocated from con3215_init(). Therefore, it needs special treatment in the probe function so it can be matched with the 3215 driver which is already owning it.

2007-10-12[S390] tape: Fix medium state handlingMichael Holzheu
Currently there are situations, where the tape medium state (loaded, unloaded, unknown) is not set correctly. The reason is that the medium association field is used to determine the medium state. This not always leads to correct results. To fix that we use another field of the medium sense data instead.

2007-10-12[S390] zcore: fix inline assembly in memcpy_real()Michael Holzheu
memcpy_real uses the mvcle instruction. This instruction alters all used registers (source, destination and 2 x count). Therefore we have to flag those registers as input/output registers (+d). In addition to that, we have to specify, that we read from memory designated by "src" and write to memory designated by "dest".

2007-10-12[S390] cio: Avoid machine check vs. not operational races.Cornelia Huck
There was the possibilty that an action like ccw_device_set_offline() triggered by a device gone machine check might trigger a not oper event. Unfortunately, this could lead to the situation that we tried to unregister a subchannel twice: Once from the slow path evaluation, and once via the not oper event. Fix this by always using the same mechanism (css_schedule_eval()) for triggering the unregister. This makes sure that unregistration will only be done once. As an added bonus, it also simplyfies the code. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-10-10lcs: Channel errors drive lcs_recovery which leads to kernel panic.Klaus D. Wacker
When the lcs irq routine detects channel failures it drives device recovery. After this event the device is no longer usable for shutdown requests, because the lcs_irq routine may get wrong channel status information. In such a case the lcs_irq routine marks the channel in 'error' state. The channel state comes back to 'running' after restarting the channels. Signed-off-by: Klaus D.

Problem: A recovery thread must not be active when device is removed. In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.
