Now that the devices present in the extended memory map are checked
against the available PA space and disabled when they don't fit,
there is no need to keep the same checks against highmem, as
highmem really is a shortcut for the PA space being 32bit.

The highmem attribute is nothing but another way to express the
PA range of a VM. To support HW that has a smaller PA range then
what QEMU assumes, pass this PA range to the virt_set_memmap()
function, allowing it to correctly exclude highmem devices
if they are outside of the PA range.

Even when the VM is configured with highmem=off, the highest_gpa
field includes devices that are above the 4GiB limit.
Similarily, nothing seem to check that the memory is within
the limit set by the highmem=off option.
This leads to failures in virt_kvm_type() on systems that have
a crippled IPA range, as the reported IPA space is larger than
what it should be.
Instead, honor the user-specified limit to only use the devices
at the lowest end of the spectrum, and fail if we have memory
crossing the 4GiB limit.

ARM64 machines like Kunpeng Family Server Chips have a level
of hardware topology in which a group of CPU cores share L3
cache tag or L2 cache. For example, Kunpeng 920 typically
has 6 or 8 clusters in each NUMA node (also represent range
of CPU die), and each cluster has 4 CPU cores. All clusters
share L3 cache data, but CPU cores in each cluster share a
local L3 tag.
Running a guest kernel with Cluster-Aware Scheduling on the
Hosts which have physical clusters, if we can design a vCPU
topology with cluster level for guest kernel and then have
a dedicated vCPU pinning, the guest will gain scheduling
performance improvement from cache affinity of CPU cluster.
So let's enable the support for this new parameter on ARM
virt machines. After this patch, we can define a 4-level
CPU hierarchy like: cpus=*,maxcpus=*,sockets=*,clusters=*,
cores=*,threads=*.

Rename the enums to match the naming style used by QAPI, and to
use "32" and "64" instead of "20" and "31". This will allow us
to more easily move the enum to the QAPI schema later.
About the naming choice: "SMBIOS 2.1 entry point"/"SMBIOS 3.0
entry point" and "32-bit entry point"/"64-bit entry point" are
synonymous in the SMBIOS specification. However, the phrases
"32-bit entry point" and "64-bit entry point" are used more often.
The new names also avoid confusion between the entry point format
and the actual SMBIOS version reported in the entry point
structure. For example: currently the 32-bit entry point
actually report SMBIOS 2.8 support, not 2.1.

Support device tree CPU topology descriptions.
In accordance with the Devicetree Specification, the Linux Doc
"arm/cpus.yaml" requires that cpus and cpu nodes in the DT are
present. And we have already met the requirement by generating
/cpus/cpu@* nodes for members within ms->smp.cpus. Accordingly,
we should also create subnodes in cpu-map for the present cpus,
each of which relates to an unique cpu node.
The Linux Doc "cpu/cpu-topology.txt" states that the hierarchy
of CPUs in a SMP system is defined through four entities and
they are socket/cluster/core/thread. It is also required that
a socket node's child nodes must be one or more cluster nodes.
Given that currently we are only provided with information of
socket/core/thread, we assume there is one cluster child node
in each socket node when creating cpu-map.

On existing older machine types, without cpu topology described
in ACPI or DT, the guest will populate one by default. With the
topology described, it will read the information and set up its
topology as instructed, but that may not be the same as what was
getting used by default. It's possible that an user application
has a dependency on the default topology and if the default one
gets changed it will probably behave differently.
Based on above consideration we'd better only describe topology
information to the guest on 6.2 and later machine types.

In the real SMP hardware topology world, it's much more likely that
we have high cores-per-socket counts and few sockets totally. While
the current preference of sockets over cores in smp parsing results
in a virtual cpu topology with low cores-per-sockets counts and a
large number of sockets, which is just contrary to the real world.
Given that it is better to make the virtual cpu topology be more
reflective of the real world and also for the sake of compatibility,
we start to prefer cores over sockets over threads in smp parsing
since machine type 6.2 for different arches.
In this patch, a boolean "smp_prefer_sockets" is added, and we only
enable the old preference on older machines and enable the new one
since type 6.2 for all arches by using the machine compat mechanism.

Type 41 defines the attributes of devices that are onboard. The
original intent was to imply the BIOS had some level of control over
the enablement of the associated devices.
If network devices are present in this table, by default, udev will
name the corresponding interfaces enoX, X being the instance number.
Without such information, udev will fallback to using the PCI ID and
this usually gives ens3 or ens4. This can be a bit annoying as the
name of the network card may depend on the order of options and may
change if a new PCI device is added earlier on the commande line.
Being able to provide SMBIOS type 41 entry ensure the name of the
interface won't change and helps the user guess the right name without
booting a first time.
This can be invoked with:
$QEMU -netdev user,id=internet
-device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \
-smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev
The PCI segment is assumed to be 0. This should hold true for most
cases.

The virt machine device plug callback currently calls
platform_bus_link_device() for any sysbus device. This is overly
broad, because platform_bus_link_device() will unconditionally grab
the IRQs and MMIOs of the device it is passed, whether it was
intended for the platform bus or not. Restrict hotpluggability of
sysbus devices to only those devices on the dynamic sysbus
allowlist.
We were mostly getting away with this because the board creates the
platform bus as the last device it creates, and so the hotplug
callback did not do anything for all the sysbus devices created by
the board itself. However if the user plugged in a device which
itself uses a sysbus device internally we would have mishandled this
and probably asserted.

After introducing non-scalar machine properties, it would be preferrable
to have a single acpitable property which includes both generic
information (such as the OEM ids) and custom tables currently
passed via -acpitable.
Do not saddle ourselves with legacy oem-id and oem-table-id
properties, instead mark them as experimental.

The virt machine already checks KVM_CAP_ARM_VM_IPA_SIZE to get the
upper bound of the IPA size. If that bound is lower than the highest
possible GPA for the machine, then QEMU will error out. However, the
IPA is set to 40 when the highest GPA is less than or equal to 40,
even when KVM may support an IPA limit as low as 32. This means KVM
may fail the VM creation unnecessarily. Additionally, 40 is selected
with the value 0, which means use the default, and that gets around
a check in some versions of KVM, causing a difficult to debug fail.
Always use the IPA size that corresponds to the highest possible GPA,
unless it's lower than 32, in which case use 32. Also, we must still
use 0 when KVM only supports the legacy fixed 40 bit IPA.

The use of FDT's is quite common across our various platforms. To
allow the guest loader to tweak it we need to make it available in
the generic state. This creates the field and migrates the initial
user to use the generic field. Other boards will be updated in later
patches.

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.
Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).
This patch allows you to override these default values.
The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN
The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.
Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.
This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

virt machine's 'smp_cpus' and machine->smp.cpus must always have the
same value. And, anywhere we have virt machine state we have machine
state. So let's remove the redundancy. Also, to make it easier to see
that machine->smp is the true source for "smp_cpus" and "max_cpus",
avoid passing them in function parameters, preferring instead to get
them from the state.
No functional change intended.

Note: "its" is currently registered conditionally, but this makes
