6286  *
6287  * When initializing and realizing a CPU object, the steps
6288  * involved in setting up CPUID data are:
6289  *
6290  * 1) Loading CPU model definition (X86CPUDefinition). This is
6291  *    implemented by x86_cpu_load_model() and should be completely
6292  *    transparent, as it is done automatically by instance_init.
6293  *    No code should need to look at X86CPUDefinition structs
6294  *    outside instance_init.
6295  *
6296  * 2) CPU expansion. This is done by realize before CPUID
6297  *    filtering, and will make sure host/accelerator data is
6298  *    loaded for CPU models that depend on host capabilities
6299  *    (e.g. "host"). Done by x86_cpu_expand_features().
6300  *
6301  * 3) CPUID filtering. This initializes extra data related to
6302  *    CPUID, and checks if the host supports all capabilities
6303  *    required by the CPU. Runnability of a CPU model is
6304  *    determined at this step. Done by x86_cpu_filter_features().
6305  *
6306  * Some operations don't require all steps to be performed.
6307  * More precisely:
6308  *
6309  * - CPU instance creation (instance_init) will run only CPU
6310  *   model loading. CPU expansion can't run at instance_init-time
6311  *   because host/accelerator data may be not available yet.
6312  * - CPU realization will perform both CPU model expansion and CPUID
6313  *   filtering, and return an error in case one of them fails.
6314  * - query-cpu-definitions needs to run all 3 steps. It needs
6315  *   to run CPUID filtering, as the 'unavailable-features'
6316  *   field is set based on the filtering results.
6317  * - The query-cpu-model-expansion QMP command only needs to run
6318  *   CPU model loading and CPU expansion. It should not filter
6319  *   any CPUID data based on host capabilities.
