linux-next: manual merge of the target-updates tree with the tree

[Stephen Rothwell]

Hi Nicholas,

Today's linux-next merge of the target-updates tree got a conflict in
drivers/scsi/virtio_scsi.c between commit b54197c43db8 ("virtio_scsi:
use cmd_size") from the scsi tree and commit 4baaa7d589e2
("virtio-scsi: Enable DIF/DIX modes in SCSI host LLD") from the
target-updates tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).
