    x86, apic: Use logical flat on intel with <= 8 logical cpus · 2fbd07a5
    Suresh Siddha 提交于
    On Intel platforms, we can use logical flat mode if there are <= 8
    logical cpu's (irrespective of physical apic id values). This will
    enable simplified and efficient IPI and device interrupt routing on
    such platforms.
    
    Fix the relevant comments while we are at it.
    
    We can clean up default_setup_apic_routing() by using apic->probe()
    but that is a different item.
