    x86, ACPI: add support for x2apic ACPI extensions · 7237d3de
    Suresh Siddha authored
    All logical processors with APIC ID values of 255 and greater will have their
    APIC reported through Processor X2APIC structure (type-9 entry type) and all
    logical processors with APIC ID less than 255 will have their APIC reported
    through legacy Processor Local APIC (type-0 entry type) only. This is the
    same case even for NMI structure reporting.
        
    The Processor X2APIC Affinity structure provides the association between the
    X2APIC ID of a logical processor and the proximity domain to which the logical
    processor belongs.
        
    For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device()
    objects in the ACPI namespace.
