When setting the APICBASE MSR to an illegal value, the APIC
implementation will return an error. This change forwards that report
to the guest as an exception rather than ignoring it when using the hvf
accelerator.

The hvf_caps data structure only exists once as part of the hvf accelerator
state, but it is initialised during vCPU initialisation. This change therefore
adds a check to ensure memory for it is only allocated once.

The handling for CPUID function 0xD (supported XSAVE features) was
improved in a recent patch. Unfortunately, this appears to have
introduced undefined behaviour for cases where ecx > 30, as the result
of (1 << idx) is undefined if idx > 30.
Per Intel SDM section 13.2, the behaviour for ecx values up to and
including 62 are specified. This change therefore specifically sets
all registers returned by the CPUID instruction to 0 for 63 and higher.
Furthermore, the bit shift uses uint64_t, where behaviour for the entire
range of 2..62 is safe and correct.

Support for x2APIC mode was recently introduced in the software emulated
APIC implementation for TCG. Enabling it when using macOS’s hvf
accelerator is useful and significantly helps performance, as Qemu
currently uses the emulated APIC when running on hvf as well.
This change wires up the read & write operations for the MSR VM exits
and allow-lists the CPUID flag in the x86 hvf runtime.

Commit b56617bbcb4 ("target/i386: Walk NPT in guest real mode") added
logic to run the page table walker even in real mode if we are in NPT
mode. That function then determined whether real mode or paging is
active based on whether the pg_mode variable was 0.
Unfortunately pg_mode is 0 in two situations:
1) Paging is disabled (real mode)
2) Paging is in 2-level paging mode (32bit without PAE)
That means the walker now assumed that 2-level paging mode was real
mode, breaking NetBSD as well as Windows XP.
To fix that, this patch adds a new PG flag to pg_mode which indicates
whether paging is active at all and uses that to determine whether we
are in real mode or not.

bindgen 0.65.0, so check for it in meson.build.
--merge-extern-blocks was added in 0.61.0.
--formatter rustfmt was added in 0.65.0 and is the default, so remove it.

Currently, we have no way to expose the arch-specific default cache
model because the cache model is sometimes related to the CPU model
(e.g., i386).
Since the user might configure "default" level, any comparison with
"default" is meaningless before the machine knows the specific level
that "default" refers to.
We can only check the correctness of the cache topology after the arch
loads the user-configured cache model from MachineState.smp_cache and
consumes the special "default" level by replacing it with the specific
level.

The x86 and ARM need to allow user to configure cache properties
(current only topology):
* For x86, the default cache topology model (of max/host CPU) does not
always match the Host's real physical cache topology. Performance can
increase when the configured virtual topology is closer to the
physical topology than a default topology would be.
* For ARM, QEMU can't get the cache topology information from the CPU
registers, then user configuration is necessary. Additionally, the
cache information is also needed for MPAM emulation (for TCG) to
build the right PPTT.
Define smp-cache related enumeration and properties in QAPI, so that
user could configure cache properties for SMP system through -machine in
the subsequent patch.
Cache enumeration (CacheLevelAndType) is implemented as the combination
of cache level (level 1/2/3) and cache type (data/instruction/unified).
Currently, separated L1 cache (L1 data cache and L1 instruction cache)
with unified higher-level cache (e.g., unified L2 and L3 caches), is the
most common cache architectures.
Therefore, enumerate the L1 D-cache, L1 I-cache, L2 cache and L3 cache
with smp-cache object to add the basic cache topology support. Other
kinds of caches (e.g., L1 unified or L2/L3 separated caches) can be
added directly into CacheLevelAndType if necessary.
Cache properties (SmpCacheProperties) currently only contains cache
topology information, and other cache properties can be added in it
if necessary.
Note, define cache topology based on CPU topology level with two
reasons:
1. In practice, a cache will always be bound to the CPU container
(either private in the CPU container or shared among multiple
containers), and CPU container is often expressed in terms of CPU
topology level.
2. The x86's cache-related CPUIDs encode cache topology based on APIC
ID's CPU topology layout. And the ACPI PPTT table that ARM/RISCV
relies on also requires CPU containers to help indicate the private
shared hierarchy of the cache. Therefore, for SMP systems, it is
natural to use the CPU topology hierarchy directly in QEMU to define
the cache topology.
With smp-cache QAPI support, add smp cache topology for machine by
parsing the smp-cache object list.
Also add the helper to access/update cache topology level of machine.

Cache topology needs to be defined based on CPU topology levels. Thus,
define CPU topology enumeration in qapi/machine.json to make it generic
for all architectures.
To match the general topology naming style, rename CPU_TOPO_LEVEL_* to
CPU_TOPOLOGY_LEVEL_*, and rename SMT and package levels to thread and
socket.
Also, enumerate additional topology levels for non-i386 arches, and add
a CPU_TOPOLOGY_LEVEL_DEFAULT to help future smp-cache object to work
with compatibility requirement of arch-specific cache topology models.

In the follow-up change, the CPU topology enumeration will be moved to
QAPI. And considerring "invalid" should not be exposed to QAPI as an
unsettable item, so, as a preparation for future changes, remove
"invalid" level from the current CPU topology enumeration structure
and define it by a macro instead.
Due to the removal of the enumeration of "invalid", bit 0 of
CPUX86State.avail_cpu_topo bitmap will no longer correspond to "invalid"
level, but will start at the SMT level. Therefore, to honor this change,
update the encoding rule for CPUID[0x1F].

This corresponds to the default when this machine was added;

[ "$target_cpu" = "microblaze" ] && target_bigendian=yes
Later commit 877fdc12b1a ("microblaze: Allow targeting

to set the CPU endianness to little-endian. Not an issue
since this property was never used, but we will use it soon,
