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] cpcmd: fix inline assembly usage.Heiko Carstens
After assigning values to specific registers memset was called. This may clobber the contents of the used registers. To solve this extract the two used inline assemblies into small functions that don't call any functions.

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] appldata_base: Remove module_exit function and modular stuffSatyam Sharma
arch/s390/Kconfig tells us that CONFIG_APPLDATA_BASE is bool and hence can never be built modular. Given this, defining appldata_exit() function is pointless (and wasteful, actually). Remove all that. Previous patch annotated appldata_offline_cpu() as __cpuexit, but now with the __exit function appldata_exit() gone, the only callsite that references it is __cpuinit, so this function can also be __cpuinit, thereby saving space when HOTPLUG_CPU=n.

2007-10-12[S390] appldata_base: Misc cpuinit annotations and bugfixSatyam Sharma
appldata_offline_cpu() is only called from __cpuinit-marked hotplug notifier callback and from the __exit-marked module_exit function, therefore candidate for __cpuexit. BTW the __exit module_exit function appldata_exit() of this driver fails to unregister_hotcpu_notifier() the notifier_block that was registered by appldata_init() during module startup. This will lead to oops if hotplug notification comes after module has been unloaded. Let's fix this by unregistering the notifier appropriately (before appldata_offline_cpu()'ing the CPUs).

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>
