This patch converts padlock-sha to use crypto_hash for its fallback.
It also changes the fallback selection to use selection by type instead
of name. This is done through the new CRYPTO_ALG_NEED_FALLBACK bit,
which is set if and only if an algorithm needs a fallback of the same
type.

Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.
This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.
Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm. The redundant check from crypto_digest_setkey
is also removed.

[PATCH 6/9] s390: qeth driver fixes [3/6]
From: Frank Pavlic <fpavlic@de.ibm.com>
fixed kernel panic caused by qeth driver:
Using a bonding device qeth driver will realloc
headroom for every skb coming from the bond device.
Once this happens qeth frees the original skb and
set the skb pointer to the new realloced skb.
Under heavy transmit workload (e.g.UDP streams) through bond
network device the qdio output queue might get full.
In this case we return with EBUSY from qeth_send_packet.
Returning to qeth_hard_start_xmit routine
the skb address on the stack still points to the old address,
which has been freed before.
Returning from qeth_hard_start_xmit with EBUSY results in
requeuing the skb. In this case it corrupts the qdisc queue
and results in kernel panic.

If there is a problem in the connection, the SCSI mid-layer will
eventually call srp_reset_host(), which will call srp_reconnect(), so
we do not need to schedule a call to srp_reconnect_work() from
srp_completion().
Removing this prevents srp_reset_host() from failing if a reconnect
scheduled from srp_completion() is already in progress, which in turn
was causing crashes as both SCSI midlayer and srp_reconnect() were
cancelling commands.
