Constraint for err is wrong since it is preinitialized and the code relies on it in case of an exception. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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". Signed-off-by:

According to C99 6.3.2.3 it's undefined what happens if a converted pointer is used to call a function whose type is not compatible with the pointed-to type. That's what the qdio code is doing, so fix it. Signed-off-by:

slab cache debugging code has been changed so that we always get a minimum alignment of the alignment of a 64-integer. Since this is 8 on s390/s390x there is no need of ARCH_KMALLOC_MINALIGN anymore. Signed-off-by:

ext_int_info_t is no longer used in entry(64).S Instead do_extint is a C function that handles the hash search. As the structure is handled in C code, we can also remove the packed attribute to avoid alignment issues. (Currently there is no alignment problem in ext_int_info_t, even if packet) Signed-off-by:

The termination condition of the loop that prints the operands of an instruction doesn't stop after the maximum of 6 operands. It continues with the operands of the next instruction format instead which create really long lines. Signed-off-by: -

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.

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).

Symptom: zcrypt fails by setting all PCIXCC/CEX2C cards offline for a certain type of invalid keys. Problem: zcrypt does not handle rc=12/rs=769 request responses correctly Solution: modify convert_type86_ica() to handle these error codes correctly Signed-off-by:Ralph Wuerthner <rwuerthn@de.ibm.com> Signed-off-by:

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:

Make sure channel path measurements are disabled via a reboot notifier since we cannot rely on userspace to disable it again after enabling it. This is 1. clean and 2. makes sure that channel path measurements do not stay enabled after a reboot not involving a subsystem reset (which would lead to the channel subsystem scribbling onto random memory).
