/***** Steps involved on loading and filtering CPUID data
*
* When initializing and realizing a CPU object, the steps
* involved in setting up CPUID data are:
*
* 1) Loading CPU model definition (X86CPUDefinition). This is
* implemented by x86_cpu_load_def() and should be completely
* transparent, as it is done automatically by instance_init.
* No code should need to look at X86CPUDefinition structs
* outside instance_init.
*
* 2) CPU expansion. This is done by realize before CPUID
* filtering, and will make sure host/accelerator data is
* loaded for CPU models that depend on host capabilities
* (e.g. "host"). Done by x86_cpu_expand_features().
*
* 3) CPUID filtering. This initializes extra data related to
* CPUID, and checks if the host supports all capabilities
* required by the CPU. Runnability of a CPU model is
* determined at this step. Done by x86_cpu_filter_features().
*
* Some operations don't require all steps to be performed.
* More precisely:
*
* - CPU instance creation (instance_init) will run only CPU
* model loading. CPU expansion can't run at instance_init-time
* because host/accelerator data may be not available yet.
* - CPU realization will perform both CPU model expansion and CPUID
* filtering, and return an error in case one of them fails.
* - query-cpu-definitions needs to run all 3 steps. It needs
* to run CPUID filtering, as the 'unavailable-features'
* field is set based on the filtering results.
* - The query-cpu-model-expansion QMP command only needs to run
* CPU model loading and CPU expansion. It should not filter
* any CPUID data based on host capabilities.
