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.

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

3f4cf6e72f [S390] cio: Avoid machine check vs. not operational races.
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.

After this event the device is no longer usable for shutdown requests,
because the lcs_irq routine may get wrong channel status information.

5705f70217 Introduce rq_for_each_segment replacing rq_for_each_bio
Every usage of rq_for_each_bio wraps a usage of
bio_for_each_segment, so these can be combined into
rq_for_each_segment.

We define "struct req_iterator" to hold the 'bio' and 'index' that
are needed for the double iteration.

54d0f56e63 qeth: Drop ARP packages on HiperSockets interface with NOARP attribute.
A network interface can get ARP packets even when the interface has
NOARP specified. In a HiperSockets environment this disturbs receiving
systems when packets are sent on the multicast queue. (E.g. TCP/IP on
z/VM issues messages reporting invalid data on the HiperSockets
interface.)
Qeth will no longer send ARP packets on HiperSockets interface when
interface has the NOARP attribute.

6e55cab9f0 qeth: provide specific message for OSA-adapters exclusively used
Exclusive usage of OSA-cards has been introduced. Even though Linux
does not make use of it, qeth should be prepared to receive a bad RC
for some initialization steps. A meaningful message is now given,
if an OSA-device is set online, even though the OSA-adapter is already
exclusively used by another host.
