    Subject[RFC PATCH v2 03/15] cpu-model: Introduce stub routine cpu_desc_avail
    Date
    This patch introduces the function cpu_desc_avail() which returns by
    default true if not architecture specific implemented. Its intention
    is to indicate if the cpu model description is available for display
    by list_cpus(). This change allows cpu model descriptions to become
    dynamically created by evaluating the runtime context instead of
    putting static cpu model information at display.
