Upon hmp_host_net_remove(), the appropriate -net client is deleted
(according to the given vlan_id and device id), as well as the
corresponsing hub port.

However, the relevant '-net' option that was added by former
hmp_host_net_add() call is still present in "net" options group.

This makes the following legit HMP sequence erroneous:

(qemu) host_net_add tap id=n1,ifname=tap1,script=no,downscript=no,vlan=1
(qemu) host_net_remove 1 n1
(qemu) host_net_add tap id=n1,ifname=tap1,script=no,downscript=no,vlan=1
Duplicate ID 'n1' for net

Fix, by deleting the stored '-net' option associated with the given
device id.

This allows increasing the rx queue size up to 1024: unlike with tx,
guests don't put in huge S/G lists into RX so the risk of running into
the max 1024 limitation due to some off-by-one seems small.

It's helpful for users like OVS-DPDK which don't do any buffering on the
host - 1K roughly matches 500 entries in tun + 256 in the current rx
queue, which seems to work reasonably well. We could probably make do
with ~750 entries but virtio spec limits us to powers of two.
It might be a good idea to specify an s/g size limit in a future
version.

It also might be possible to make the queue size smaller down the road, 64
seems like the minimal value which will still work (as guests seem to
assume a queue full of 1.5K buffers is enough to process the largest
incoming packet, which is ~64K).  No one actually asked for this, and
with virtio 1 guests can reduce ring size without need for host
configuration, so don't bother with this for now.

Add AMD IOMMU emulaton to Qemu in addition to Intel IOMMU.
The IOMMU does basic translation, error checking and has a
minimal IOTLB implementation. This IOMMU bypassed the need
for target aborts by responding with IOMMU_NONE access rights
and exempts the region 0xfee00000-0xfeefffff from translation
as it is the q35 interrupt region.

We advertise features that are not yet implemented to please

IOTLB aims at implementing commands on real IOMMUs which is
essential for debugging and may not offer any performance

The virtio code uses int, unsigned int, and uint16_t for virtqueue
indices.  The uint16_t is used for the low-level descriptor layout in
virtio_ring.h while code that isn't concerned with descriptor layout can
use unsigned int.

Use of int is problematic because it can result in signed/unsigned
comparison and incompatible int*/unsigned int* pointer types.

Make the virtqueue_get_avail_bytes() 'i' variable unsigned int.  This
eliminates the need to introduce casts and modify code further in the
patches that follow.

QEMU prints an error message and exits when the device enters an invalid
state.  Terminating the process is heavy-handed.  The guest may still be
able to function even if there is a bug in a virtio guest driver.

Moreover, exiting is a bug in nested virtualization where a nested guest
could DoS other nested guests by killing a pass-through virtio device.
I don't think this configuration is possible today but it is likely in
the future.

If the broken flag is set, do not process virtqueues or write back used
descriptors.  The broken flag can be cleared again by resetting the
device.

ppc patch queue 2016-09-23

This pull request supersedes ppc-for-2.8-20160922.  There was a clang
build error in that, and I've also added one extra patch in the new pull.

Included in this set of ppc and spapr patches are:
    * TCG implementations for more POWER9 instructions
    * Some preliminary XICS fixes in preparataion for the pnv machine type
    * A significant ADB (Macintosh kbd/mouse) cleanup
    * Some conversions to use trace instead of debug macros
    * Fixes to correctly handle global TLB flush synchronization in
      TCG.  This is already a bug, but it will have much more impact
      when we get MTTCG
    * Add more qtest testcases for Power
    * Some MAINTAINERS updates
    * Assorted bugfixes
    * Add the basics of NUMA associativity to the spapr PCI host bridge

This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.

With this patch, blockdev-add always works on a node level, i.e. it
creates a BDS, but no BB. Consequently, x-blockdev-del doesn't need the
'device' option any more, but 'node-name' becomes mandatory.

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.

Even for nodes that have a BlockBackend attached, bdrv_get_parent_name()
can return NULL if the BB is anonymous (e.g. it belongs to a block job
or a device that was created with a drive=<node-name> option).

Remove the information from the error message. The user probably knows
already why the node is still in use.

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.

Some test cases that used to work with an unattached BlockBackend are
removed, either because they don't make sense with an attached device or
because the equivalent test case with an attached device already exists.

The test cases that test conflicts between the 'id' option to
blockdev-add and existing block devices or the 'node-name' of the same
command can be removed because it won't be possible to specify this at
the end of the series.
