Hi,
here's another kvm-s390 bugfix for kvm-next, this time fixing a
thinko in the I/O interrupt injection.
Please apply.

There are two ways to express an interruption subclass:
- As a bitmask, as used in cr6.
- As a number, as used in the I/O interruption word.
Unfortunately, we have treated the I/O interruption word as if it
contained the bitmask as well, which went unnoticed so far as

This is useful in places that recycle the same scatterlist multiple
times, and do not want to incur the cost of sg_init_table every

Jens, could you give your Acked-by for this patch?
Eliminate the code duplication between virtqueue_add_buf and
virtqueue_add_sg. That's safe to do now that no devices will
pass scatterlists with a termination marker in the middle.

Using the new virtio_scsi_add_sg function lets us simplify the queueing
path. In particular, all data protected by the tgt_lock is just gone
(multiqueue will find a new use for the lock).
The speedup is relatively small (2-4%) but it is worthwhile because of
the code simplification it enables.
The virtqueue_add_buf function has two limitations:
1) it requires the caller to provide all the buffers in a single call;
2) it does not support chained scatterlists: the buffers must be
provided as an array of struct scatterlist.
Because of these limitations, virtio-scsi has to copy each
Right now, both virtblk_add_req and virtblk_add_req_wait call
virtqueue_add_buf. To prepare for the next patches, abstract the call
to virtqueue_add_buf into a new function __virtblk_add_req, and include
the waiting logic directly in virtblk_add_req.

This is similar to the previous patch, but a bit more radical
because the bio and req paths now share the buffer construction
code. Because the req path doesn't use vbr-sg, however, we
need to add a couple of arguments to __virtblk_add_req.
We also need to teach __virtblk_add_req how to build
Prepare for when virtqueue_add_buf will use sg_next instead of
ignoring ending markers.
Note that for_each_sg (and thus virtqueue_add_buf) allows you
to pass a truncated scatterlist that does not have a marker
on the last item. We rely on this in add_recvbuf_mergeable.

Move the creation of the request header and response footer to
__virtblk_add_req. vbr-sg only contains the data scatterlist,
the header/footer are added separately using the new piecewise
API for building virtqueue buffers.
