It is valid to have a 48-character model ID on CPUID, however the
definition of X86CPUDefinition::model_id is char[48], which can
make the compiler drop the null terminator from the string.
If a CPU model happens to have 48 bytes on model_id, "-cpu help"
will print garbage and the object_property_set_str() call at
x86_cpu_load_def() will read data outside the model_id array.
We could increase the array size to 49, but this would mean the
compiler would not issue a warning if a 49-char string is used by
mistake for model_id.
To make things simpler, simply change model_id to be const char*,
and validate the string length using an assert() on
x86_cpu_cpudef_class_init.

Oops, this patch makes 486, pentium, pentium2, pentium3 and
athlon crash because they don't have model_id explicitly set.
Fixup:
* Set model_id to "" explicitly on 486, pentium* and athlon (fix crash)
* Change assert() to ensure model_id is not NULL
* Move assert() to x86_register_cpudef_type() (closer to existing
assert() that validates CPUID_EXT2_AMD_ALIASES)

Don't we need to pass-through cupid_7_edx to guest when configuring '-cpu host'?
Otherwise how guests use IBPB/IBRS/STIPB capabilities?

We already do. See the check for cpu->max_features at
x86_cpu_expand_features().
Do you see something else missing?

The new MSR IA32_SPEC_CTRL MSR was introduced by a recent Intel
microcode updated and can be used by OSes to mitigate
CVE-2017-5715. Unfortunately we can't change the existing CPU
models without breaking existing setups, so users need to
explicitly update their VM configuration to use the new *-IBRS
CPU model if they want to expose IBRS to guests.
The new CPU models are simple copies of the existing CPU models,
with just CPUID_7_0_EDX_SPEC_CTRL added and model_id updated.

RFC NOTE: More info is required to confirm if this is necessary
to mitigate mitigate CVE-2017-5715 on AMD CPUs.
EPYC-IBPB is a copy of the EPYC CPU model with
just CPUID_8000_0008_EBX_IBPB added.

RFC NOTE: we need to confirm if all
Westmere/SandyBridge/IvyBridge CPUs out there support PCID,
before applying this patch.
RFC NOTE 2: in parallel, we are evaluating the possibility of
enabling PCID on the existing Westmere/SandyBridge/IvyBridge CPU
models, see
https://patchew.org/QEMU/20180108205052.24385-1-vincent@bernat.im/
and
https://patchew.org/QEMU/20180109070112.30806-1-vincent@bernat.im/
PCID was already available on Westmere, SandyBridge and
IvyBridge, but we can't easily add it to the existing CPU models
without breaking libvirt expectations about CPU model runnability
(a runnable CPU model shouldn't become runnable just because of a
machine-type or QEMU upgrade).
However, Westmere-IBRS, SandyBridge-IBRS and IvyBridge-IBRS are
new CPU models, so we can safely add PCID to them.
Note that PCID is not necessary to mitigate Meltdown and/or
Spectre, but it is really helpful to make performance not suffer
when enabling KPTI on guest kernels.
