Hi Rafael, Thanks for previous review for v1. Later on I thought acpi_lapic is more suitable for checking whether LAPIC in MADT is available, and it can hanlde both the UP system running SMP kernel with no LAPIC in MADT and kdump kernel after multiple CPUs system crashed on non-1st CPU. I tested

In acpi_processor_get_info(), acpi processor info is initialized including id, namely cpu index. Currently, if on UP system running SMP kerenl with no LAPIC in MADT, cpu0_initialized is checked if acpi processor id is initialized. However this check maybe is not correct for kdump kernel. Most of
