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.

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

Problem: zcrypt does not handle rc=12/rs=769 request responses correctly
Solution: modify convert_type86_ica() to handle these error codes correctly

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.

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).

Need to read and store sblk->status_idx before checking for more work.
The status idx is later written back to the hardware when enabling
interrupts to acknowledge how much work has been processed. If the
order is reversed, we can end up acknowledging work we haven't
processed.
When completing bnx2_poll(), we should always break out of the while
loop and return work_done instead of returning 0.
