436d1bc7fe [S390] dcssblk: prevent early access without own make_request function
When loading a dcss segment with the dcssblk driver, sometimes the
following kind of message appears:

bio too big device dcssblk0 (8 > 0)
Buffer I/O error on device dcssblk0, logical block 172016
..

The fix is to move the disk registration after setting the
make_request function, to avoid calls into generic_make_request
for dcssblock without having the make_request function set up
properly.

c94dec99f9 [S390] cio: Issue SenseID per path.
We may receive a unit check for every path when we issue a SenseID.
Unfortunately, the channel subsystem will try on a different path
every time if we use a lpm of 0xff, which will exhaust our retry
counter.

Therefore, revert SenseID to its previous per-path behaviour and
just leave out the suspend multipath reconnect.

86e8dfc560 [SCSI] zfcp: fix cleanup of dismissed error recovery actions
Calling zfcp_erp_strategy_check_action() after zfcp_erp_action_to_running()
in zfcp_erp_strategy() might cause an unbalanced up() for erp_ready_sem,
which makes the zfcp recovery fail somewhere along the way:

erp thread processing erp_action:
|
|	someone waking up erp thread for erp_action
|	|
|	|		someone else dismissing erp_action:
|	|		|
V	V		V

	write_lock_irqsave(&adapter->erp_lock, flags);
	...
	if (zfcp_erp_action_exists(erp_action) == ZFCP_ERP_ACTION_RUNNING) {
		zfcp_erp_action_to_ready(erp_action);
		up(&adapter->erp_ready_sem);	/* first up() for erp_action */
	}
	write_unlock_irqrestore(&adapter->erp_lock, flags);

write_lock_irqsave(&adapter->erp_lock, flags);
...
zfcp_erp_action_to_running(erp_action);
write_unlock_restore(&adapter->erp_lock, flags);
/* processing erp_action */

			write_lock_irqsave(&adapter->erp_lock, flags);
			...
			erp_action->status |= ZFCP_STATUS_ERP_DISMISSED;
			if (zfcp_erp_action_exists(erp_action) ==
						ZFCP_ERP_ACTION_RUNNING) {
				zfcp_erp_action_to_ready(erp_action);
				up(&adapter->erp_ready_sem);
				/* second, unbalanced up() for erp_action */
			}
			...
			write_unlock_restore(&adapter->erp_lock, flags);

write_lock_irqsave(&adapter->erp_lock, flags);
if (erp_action->status & ZFCP_STATUS_ERP_DISMISSED) {
	zfcp_erp_action_dequeue(erp_action);
	retval = ZFCP_ERP_DISMISSED;
}
...
write_unlock_restore(&adapter->erp_lock, flags);
down(&adapter->erp_ready_sem);
/* this down() is meant to balance the first up() */

The erp thread must not dismiss an erp_action after moving that action to
erp_running_head. Instead it should just go through the down() operation,
which balances the first up(), and run through zfcp_erp_strategy one more
time for the second up(), which eventually cleans up erp_action. Which
is similar to the normal processing of an event for erp_action doing
something asynchronously (e.g. waiting for the completion of an fsf_req).

This only works if we make sure that a dismissed erp_action is passed to
zfcp_erp_strategy() prior to the other action, which caused actions to be
dismissed. Therefore the patch implements this rule: running actions go to
the head of the ready list; new actions go to the tail of the ready list;
the erp thread picks actions to be processed from the ready list's head.

d0076f7754 [SCSI] zfcp: fix dismissal of error recovery actions
zfcp_erp_action_dismiss() used to ignore any actions in the ready list. This
is a bug. Any action superseded by a stronger action needs to be dismissed.
This patch changes zfcp_erp_action_dismiss() so that it dismisses actions
regardless of their list affiliation. The ERP thread is able to handle this.
It is important to kick the erp thread only for actions in the running list,
though, as an imbalance of wakeup signals would confuse the erp thread
otherwise.

0fc3ddd67a [S390] Fix smsgiucv init on no iucv machines
smsgiucv is a driver that relies on iucv to work properly. If
iucv ans smsgiucv are compiled into the kernel and run on an
lpar the following scenario happens:
iucv is initialized early as a subsystem. It checks for z/VM and
returns with EPROTONOTSUPPORT. Later smsgiucv tries to run
driver_register with iucv_bus as bus. As this bus is not
initialized the driver core and list debugging issue several
warnings and oopses.

Solution is to let smsgiucv also check for z/VM and return
EPROTONOTSUPPORT as well.

04c7197650 unicode diacritics support
There have been issues with non-latin1 diacritics and unicode.
http://bugzilla.kernel.org/show_bug.cgi?id=7746

Git 759448f459 `Kernel utf-8 handling'
partly resolved it by adding conversion between diacritics and
unicode. The patch below goes further by just turning diacritics into
unicode, hence providing better future support. The kbd support can be
fetched from
http://bugzilla.kernel.org/attachment.cgi?id=12313

This was tested in all of latin1, latin9, latin2 and unicode with french
and czech dead keys.

Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR
and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR.

New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit
_input_.  No, we don't want to store the translation, as it is potentially
sparse and large.

7eff2e7a8b Driver core: change add_uevent_var to use a struct
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.

a2e5380197 [S390] 3215: Handle special console device.
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.

1b9fd76e30 [S390] tape: Fix medium state handling
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.

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".
