We register a simple trigger so make sure we use the corresponding

Big thanks go to Mathias Kolehmainen for reporting the bug, providing
debug output and testing the patches I sent him to get it working.

The fix was to stop calling ntfs_attr_set() at mount time as that causes
balance_dirty_pages_ratelimited() to be called which on systems with
little memory actually tries to go and balance the dirty pages which tries
to take the s_umount semaphore but because we are still in fill_super()
across which the VFS holds s_umount for writing this results in a
deadlock.

We now do the dirty work by hand by submitting individual buffers.  This
has the annoying "feature" that mounting can take a few seconds if the
journal is large as we have clear it all.  One day someone should improve
on this by deferring the journal clearing to a helper kernel thread so it
can be done in the background but I don't have time for this at the moment
and the current solution works fine so I am leaving it like this for now.

Introduce a consistent style in vmlinux.lds.
This style is gradually being introduced for all archs.

A few lables were moved inside the section definition so
they are assigned the correct value of gcc decide to align
the content to another address than the one . has.
In the past this has fixed several bugs but for s390 it
will not impact due to all the alignmnet already introduced.

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).

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.
