commit 9b70c179
    virtio-serial: switch to standard-headers

changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.

As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.

As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.

Long terms we probably want something along the lines
of virtio_net_set_config_size.

This does not bother DMA, because DMA generally transfers
the entire SGList in one shot if it can.

PIO, on the other hand, tries to transfer just one sector
at a time, and will make multiple visits to the sglist

start/end_exclusive() need be pairs, except the start_exclusive() in
stop_all_tasks() which is only used by force_sig(), which will be abort.
So at present, start_exclusive() in stop_all_task() need not be paired.

queue_signal() may call force_sig(), or return after kill pid (or queue
signal). If could return from queue_signal(), stop_all_task() would not
be called in time, the next end_exclusive() would be issue.

With the Intel microcode update that removed HLE and RTM, there will be

have the HLE and RTM features, and some that don't have the HLE and RTM
features. On both cases people may be willing to use the pc-*-2.3

So, to cover both cases, introduce Haswell-noTSX and Broadwell-noTSX CPU

We need all possible CPUs (including hotplug ones) to be present in the
SRAT when QEMU starts. QEMU already does that correctly today, the only
problem is that when a CPU is omitted from the NUMA configuration, it is
silently assigned to node 0.

Check if all CPUs up to max_cpus are present in the NUMA configuration
and warn about missing CPUs.

Make it just a warning, to allow management software to be updated if
necessary. In the future we may make it a fatal error instead.

Command-line examples:

* Correct, no warning:

  $ qemu-system-x86_64 -smp 2,maxcpus=4
  $ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0-3

* Incomplete, with warnings:

  $ qemu-system-x86_64 -smp 2,maxcpus=4 -numa node,cpus=0
  qemu-system-x86_64: warning: CPU(s) not present in any NUMA nodes: 1 2 3
  qemu-system-x86_64: warning: All CPU(s) up to maxcpus should be described in NUMA config

v4 -> v5:
 * Commit log update, to make problem description clearer

Since commit
   dd0247e0 pc: acpi: mark all possible CPUs as enabled in SRAT
Linux kernel actually tries to use CPU to Node mapping from
QEMU provided SRAT table instead of discarding it, and that
in some cases breaks build_sched_domains() which expects
sane mapping where cores/threads belonging to the same socket
are on the same NUMA node.

With current default round-robin mapping of VCPUs to nodes
guest ends-up with cores/threads belonging to the same socket
being on different NUMA nodes.

For example with following CLI:

   qemu-system-x86_64 -m 4G \
         -cpu Opteron_G3,vendor=AuthenticAMD \
         -smp 5,sockets=1,cores=4,threads=1,maxcpus=8 \
         -numa node,nodeid=0 -numa node,nodeid=1

2.6.32 based kernels will hang on boot due to incorrectly built
sched_group-s list in update_sd_lb_stats()

Replacing default mapping with a manual, where VCPUs belonging to
the same socket are on the same NUMA node, fixes the issue for
guests which can't handle nonsense topology i.e. changing CLI to:
  -numa node,nodeid=0,cpus=0-3 -numa node,nodeid=1,cpus=4-7

So instead of simply scattering VCPUs around nodes, provide
callback to map the same socket VCPUs to the same NUMA node,
which is what guests would expect from a sane hardware/BIOS.

Users of virtio-serial may want to know when a port becomes writable.  A
port can stop accepting writes if the guest port is open but not being
read from.  In this case, data gets queued up in the virtqueue, and
after the vq is full, writes to the port do not succeed.

When the guest reads off a vq element, and adds a new one for the host
to put data in, we can tell users the port is available for more writes,
via the new ->guest_writable() callback.
