Most list head structs need not be given a name. In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed. In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct. So clean up everything, not giving a
name except in the rare case where it is necessary.

The code had asserted an interrupt every time it was requested to check
for new completion queue entries.This can result in spurious interrupts
seen by the guest OS.
Fix this by asserting an interrupt only if there are un-acknowledged
completion queue entries available.

When the submission and completion queues are being torn down
the IRQ will be asserted for the completion queue when the
submsission queue is deleted. Then when the completion queue
is deleted it stays asserted. Thus, on systems that do
not use MSI, no further interrupts can be triggered on the host.
Linux sees this as a long delay when unbinding the nvme device.
Eventually the interrupt timeout occurs and it continues.
To fix this we ensure we deassert the IRQ for a CQ when it is
deleted.

The CMB is marked as DEVICE_LITTLE_ENDIAN, so the data must be
read/written as if it was little-endian output (in the case of
big endian, we get two swaps, one in the memory core and one
in nvme.c).

Signed-off-by: Kevin Wolf <kwolf@redhat.com>
Because the CMB BAR has a min_access_size of 2, if you read the last
byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
error. This is CVE-2018-16847.
Another way to fix this might be to register the CMB as a RAM memory
region, which would also be more efficient. However, that might be a
change for big-endian machines; I didn't think this through and I don't
know how real hardware works. Add a basic testcase for the CMB in case
somebody does this change later on.

Commit c8a35f1cf0 "fdc: use IsaDma interface instead of global DMA_*
functions" accidentally introduced a segfault in fdctrl_stop_transfer() for
non-DMA transfers.
If fdctrl->dma_chann has not been configured then the fdctrl->dma interface
reference isn't initialised during isabus_fdc_realize(). Unfortunately
fdctrl_stop_transfer() unconditionally references the DMA interface when
finishing the transfer causing a NULL pointer dereference.
Fix the issue by adding a check in fdctrl_stop_transfer() so that the DMA
interface reference and release method is only invoked if fdctrl->dma_chann
has been set.
(This issue was discovered by Martin testing a recent change in the NetBSD
installer under qemu-system-sparc)

Read only feature shouldn't be negotiable, because if the
backend device reported Read only feature supported, QEMU
host driver shouldn't change backend's RO attribute. While
here, also enable the vhost-user-blk test utility to test
RO feature.

This is only half of the work, because the proxy devices (virtio-*-pci,
virtio-*-ccw, etc.) are still included unconditionally. It is still a
move in the right direction.

When multi queue is enabled e.g. for a virtio-net device,
each queue pair will have a vhost_dev, and the only thing
shared between vhost devs currently is the chardev. This
patch introduces a vhost-user state structure which will
be shared by all vhost devs of the same virtio device.

Certain functions in xen_disk are called with a pointer to xendev
(struct XenDevice *). They then use container_of() to acces the surrounding
blkdev (struct XenBlkDev) but then in various places use &blkdev->xendev
when use of the original xendev pointer is shorter to express and clearly
equivalent.
This patch is a purely cosmetic patch which makes sure there is a xendev
pointer on stack for any function where the pointer is need on multiple
occasions modified those functions to use it consistently.

Since xen_disk now always copies data to and from a guest there is no need
to maintain a vector entry corresponding to every page of a request.
This means there is less per-request state to maintain so the ioreq
structure can shrink significantly.
