/***** 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_model() 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.
