4983  *
4984  * When initializing and realizing a CPU object, the steps
4985  * involved in setting up CPUID data are:
4986  *
4987  * 1) Loading CPU model definition (X86CPUDefinition). This is
4988  *    implemented by x86_cpu_load_def() and should be completely
4989  *    transparent, as it is done automatically by instance_init.
4990  *    No code should need to look at X86CPUDefinition structs
4991  *    outside instance_init.
4992  *
4993  * 2) CPU expansion. This is done by realize before CPUID
4994  *    filtering, and will make sure host/accelerator data is
4995  *    loaded for CPU models that depend on host capabilities
4996  *    (e.g. "host"). Done by x86_cpu_expand_features().
4997  *
4998  * 3) CPUID filtering. This initializes extra data related to
4999  *    CPUID, and checks if the host supports all capabilities
5000  *    required by the CPU. Runnability of a CPU model is
5001  *    determined at this step. Done by x86_cpu_filter_features().
5002  *
5003  * Some operations don't require all steps to be performed.
5004  * More precisely:
5005  *
5006  * - CPU instance creation (instance_init) will run only CPU
5007  *   model loading. CPU expansion can't run at instance_init-time
5008  *   because host/accelerator data may be not available yet.
5009  * - CPU realization will perform both CPU model expansion and CPUID
5010  *   filtering, and return an error in case one of them fails.
5011  * - query-cpu-definitions needs to run all 3 steps. It needs
5012  *   to run CPUID filtering, as the 'unavailable-features'
5013  *   field is set based on the filtering results.
5014  * - The query-cpu-model-expansion QMP command only needs to run
5015  *   CPU model loading and CPU expansion. It should not filter
5016  *   any CPUID data based on host capabilities.
