    x86: Always use x86_cpu_to_logical_apicid for cpu -> logical apic id · 6f802c4b
    Tejun Heo authored
    Currently, cpu -> logical apic id translation is done by
    apic->cpu_to_logical_apicid() callback which may or may not use
    x86_cpu_to_logical_apicid.  This is unnecessary as it should
    always equal logical_smp_processor_id() which is known early
    during CPU bring up.
    
    Initialize x86_cpu_to_logical_apicid after apic->init_apic_ldr()
    in setup_local_APIC() and always use x86_cpu_to_logical_apicid
    for cpu -> logical apic id mapping.
