    x86/apic, ACPI: Remove the repeated lapic address override entry parsing · 6de42119
    Baoquan He authored
    The ACPI MADT has a 32-bit field providing lapic address at which
    each processor can access its lapic information. MADT also contains
    an optional entry to provide a 64-bit address to override the 32-bit
    one. However the current code does the lapic address override entry
    parsing twice. One is in early_acpi_boot_init() because AMD NUMA need
    get boot_cpu_id earlier. The other is in acpi_boot_init() which parses
    all MADT entries.
    
    So in this patch we remove the repeated code in the 2nd part.
    
    Meanwhile print lapic override entry information like other MADT entry,
    this will be added to boot log.
    
    This patch is not supposed to change any runtime behavior, other than
    improving kernel messages.
