The check on kvm_enable_x2apic() needs to happen *anyway* in order to

elsewhere.

Firstly, we need KVM to support the X2APIC API in order to allow IRQ
delivery to APICs >= 255. So we need to call/check kvm_enable_x2apic(),
which was done elsewhere in *some* cases but not all.
Secondly, microvm needs the same check. So move it from pc_machine_done()
to x86_cpus_init() where it will work for both.
The check in kvm_cpu_instance_init() is now redundant and can be dropped.

The CXL Early Discovery Table is defined in the CXL 2.0 specification as
a way for the OS to get CXL specific information from the system
firmware.
CXL 2.0 specification adds an _HID, ACPI0016, for CXL capable host
bridges, with a _CID of PNP0A08 (PCIe host bridge). CXL aware software
is able to use this initiate the proper _OSC method, and get the _UID
which is referenced by the CEDT. Therefore the existence of an ACPI0016
device allows a CXL aware driver perform the necessary actions. For a
CXL capable OS, this works. For a CXL unaware OS, this works.
CEDT awaremess requires more. The motivation for ACPI0017 is to provide
the possibility of having a Linux CXL module that can work on a legacy
Linux kernel. Linux core PCI/ACPI which won't be built as a module,
will see the _CID of PNP0A08 and bind a driver to it. If we later loaded
a driver for ACPI0016, Linux won't be able to bind it to the hardware
because it has already bound the PNP0A08 driver. The ACPI0017 device is
an opportunity to have an object to bind a driver will be used by a
Linux driver to walk the CXL topology and do everything that we would
have preferred to do with ACPI0016.
There is another motivation for an ACPI0017 device which isn't
implemented here. An operating system needs an attach point for a
non-volatile region provider that understands cross-hostbridge
interleaving. Since QEMU emulation doesn't support interleaving yet,
this is more important on the OS side, for now.
As of CXL 2.0 spec, only 1 sub structure is defined, the CXL Host Bridge
Structure (CHBS) which is primarily useful for telling the OS exactly
where the MMIO for the host bridge is.

The second bit of IAPC_BOOT_ARCH in FADT table indicates the presence of
keyboard controller implemented as 8042 or equivalent micro controller. This
change enables this flag for microvms if such a device exists (for example,
when added explicitly from the QEMU commandline). Change
654701e292d98b308b0 ("hw/acpi: add indication for i8042 in IA-PC boot flags of the FADT table")
enabled this flag for i386 q35 based machines. The reason for doing the same
for micro-vms is to make sure we provide the correct tables to the guest OS
uniformly in all cases when an i8042 device is present. When this bit is not
enabled, guest OSes has to find other indirect methods to detect the device
which we would like to avoid.

This can allow the guest OS to determine more easily if i8042 controller
is present in the system or not, so it doesn't need to do probing of the
controller, but just initialize it immediately, before enumerating the
ACPI AML namespace.
The 8042 bit in IAPC_BOOT_ARCH was introduced from ACPI spec v2 (FADT
revision 2 and above). Therefore, in this change, we only enable this bit for
x86/q35 machine types since x86/i440fx machines use FADT ACPI table with
revision 1.

COMPAT_PROP_PCP is 'on' by default and it's used for turning
off PCP capability on PCIe slots for 2.0 machine types using
compat machinery.
Drop not needed compat glue as Q35 supports migration starting
from 2.4 machine types.

commit
f862ddbb1a (hw/i386: Remove the deprecated pc-1.x machine types)
removed the last user of broken APIC ID compat knob,
but compat_apic_id_mode itself was forgotten.
Clean it up and simplify x86_cpu_apic_id_from_index()

On some older software like Windows 7 installer, having both a PS/2
mouse and USB mouse results in only one device working property (which
might be a different device each boot). While the workaround to not use
a USB mouse with such software is valid, it creates an inconsistent
experience if the user wishes to always use a USB mouse.
This introduces a new machine property to inhibit the creation of the
i8042 PS/2 controller.

The list of machine types grows larger and larger each release ... and
it is unlikely that many people still use the very old ones for live
migration. QEMU v1.7 has been released more than 8 years ago, so most
people should have updated their machines to a newer version in those
8 years at least once. Thus let's mark the very old 1.x machine types
as deprecated now.

Replce the literal magic number 48 with length calculation (32 bytes at
the end of the firmware after the table footer + 16 bytes of the OVMF
table footer GUID).
No functional change intended.

When pc_system_parse_ovmf_flash() parses the optional GUIDed table in
the end of the OVMF flash memory area, the table length field is checked
for sizes that are too small, but doesn't error on sizes that are too
big (bigger than the flash content itself).
Add a check for maximal size of the OVMF table, and add an error report
in case the size is invalid. In such a case, an error like this will be
displayed during launch:
qemu-system-x86_64: OVMF table has invalid size 4047
and the table parsing is skipped.
