Currently, it always returns 0, no need to check the return value at all.
In addition, enter colo coroutine only if migration_incoming_colo_enabled()
is true.
Once the destination side enters the COLO* state, the COLO process will
take over the remaining processes until COLO exits.

b17a26bc4b i386: Support module_id in X86CPUTopoIDs
Add module_id member in X86CPUTopoIDs.

module_id can be parsed from APIC ID, so also update APIC ID parsing
rule to support module level. With this support, the conversions with
module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are
completed.

module_id can be also generated from cpu topology, and before i386
supports "modules" in smp, the default "modules per die" (modules *
clusters) is only 1, thus the module_id generated in this way is 0,
so that it will not conflict with the module_id generated by APIC ID.

3568adc995 i386: Support modules_per_die in X86CPUTopoInfo
Support module level in i386 cpu topology structure "X86CPUTopoInfo".

Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.

Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.

In addition, update topology structure in test-x86-topo.c.

6ddeb0ec8c i386/cpu: Introduce bitmap to cache available CPU topology levels
Currently, QEMU checks the specify number of topology domains to detect
if there's extended topology levels (e.g., checking nr_dies).

With this bitmap, the extended CPU topology (the levels other than SMT,
core and package) could be easier to detect without touching the
topology details.

This is also in preparation for the follow-up to decouple CPUID[0x1F]
subleaf with specific topology level.

a44ea3fa7f hw/i386/pc_sysfw: Alias rather than copy isa-bios region
In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped
to the top of the 4G memory boundary. Do the same in the -pflash case, but only
for new machine versions for migration compatibility. This establishes common
behavior and makes pflash commands work in the "isa-bios" region which some
real-world legacy bioses rely on.

Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash
case will now also point to encrypted memory, just like it already does in the
-bios case.

When running `info mtree` before and after this commit with
`qemu-system-x86_64 -S -drive \
if=pflash,format=raw,readonly=on,file=/usr/share/qemu/bios-256k.bin` and running
`diff -u before.mtree after.mtree` results in the following changes in the

Emit VFIO migration QAPI event when a VFIO device changes its migration
state. This can be used by management applications to get updates on the
current state of the VFIO device for their own purposes.

A new per VFIO device capability, "migration-events", is added so events
can be enabled only for the required devices. It is disabled by default.

66f3b79e85 accel/tcg: Hide in_same_page outside of a target-specific context

TARGET_PAGE_MASK, the function is not really required outside
the context of target-specific translation.

This makes the header usable by target independent code.
