The open function of qeth is not executed if the qeth device is in
state DOWN or HARDSETUP. A recovery switches from state SOFTSETUP to
HARDSETUP to DOWN to HARDSETUP and back to SOFTSETUP. If open and
recover are running concurrently, open fails if it hits the states
HARDSETUP or DOWN. This patch inserts waiting for recovery finish
in the qeth open functions to enable successful qeth device opening
in spite of a running recovery.

A race condition exists in the ccwgroup device unregistration code
which can cause a kernel panic due to a use-after-free bug. This
race condition might be triggered when all ccw devices associated with
a ccwgroup device are removed at the same time (e.g. because the
corresponding channel path becomes no longer available).
Fix this race condition by clearing the references from the associated
ccw devices to the ccw group device during unregistration of the
ccw group device.

this restriction by allocating allmost twice as much memory as
actually needed, so that in any case there is enough room for the full

Introduce a scan treshold for the qdio outbound queues. By setting the
threshold the driver can tell qdio after how much used SBALs qdio
should schedule the outbound tasklet that scans the queue for finished
SBALs. The threshold is specific by the drivers because a
Hipersockets device is much faster in utilizing outbound buffers than a
ZFCP or OSA device.
The default values after how many used SBALs the tasklet should run are:
OSA: > 31 SBALs
Hipersockets: > 7 SBALs
zfcp: > 55 SBALs

If the shared indicator is used the following race leads to
an inbound stall:
Device CPU0 CPU1
========================================================
non-shared DSCI =>1
ALSI => 1
Thin INT
ALSI => 0
non-shared DSCI
tasklets scheduled
shared DSCI => 1
ALSI => 1
shared DSCI => 0
ALSI ? -> set
Thin INT
ALSI => 0
ALSI was set,
shared DSCI => 1
After that no more interrupts occur because the DSCI is still set.
Fix that race by only resetting the shared DSCI if it was actually
set so the tasklets for all shared devices are scheduled and will
run after the interrupt.

The cca on the crypto adapter has a restriction in the size of the
exponent if a key with a modulus bigger than 2048 bit is used. Thus
in that case we have to avoid that the crypto device driver thinks
the adapter is defect and sets it offline. Therfore a new member for
the zcrypt_device struct called max_exp_bit_length is introduced. This
will be set the first time the cca returns the error code function
not implemented. If this is done with an adapter twice it will return
