6390  *
6391  * When initializing and realizing a CPU object, the steps
6392  * involved in setting up CPUID data are:
6393  *
6394  * 1) Loading CPU model definition (X86CPUDefinition). This is
6395  *    implemented by x86_cpu_load_model() and should be completely
6396  *    transparent, as it is done automatically by instance_init.
6397  *    No code should need to look at X86CPUDefinition structs
6398  *    outside instance_init.
6399  *
6400  * 2) CPU expansion. This is done by realize before CPUID
6401  *    filtering, and will make sure host/accelerator data is
6402  *    loaded for CPU models that depend on host capabilities
6403  *    (e.g. "host"). Done by x86_cpu_expand_features().
6404  *
6405  * 3) CPUID filtering. This initializes extra data related to
6406  *    CPUID, and checks if the host supports all capabilities
6407  *    required by the CPU. Runnability of a CPU model is
6408  *    determined at this step. Done by x86_cpu_filter_features().
6409  *
6410  * Some operations don't require all steps to be performed.
6411  * More precisely:
6412  *
6413  * - CPU instance creation (instance_init) will run only CPU
6414  *   model loading. CPU expansion can't run at instance_init-time
6415  *   because host/accelerator data may be not available yet.
6416  * - CPU realization will perform both CPU model expansion and CPUID
6417  *   filtering, and return an error in case one of them fails.
6418  * - query-cpu-definitions needs to run all 3 steps. It needs
6419  *   to run CPUID filtering, as the 'unavailable-features'
6420  *   field is set based on the filtering results.
6421  * - The query-cpu-model-expansion QMP command only needs to run
6422  *   CPU model loading and CPU expansion. It should not filter
6423  *   any CPUID data based on host capabilities.
