    Subject[PATCH 02/15] x86, apic: Fix lapic mapping with construct ISA and visws mptable path
    Date
    Do need to set lapic mapping for them

    in arch/x86/kernel/visws_quirks.c:
    we only have visws_find_smp_config() to set mp_lapic_addr to APIC_DEFAULT_PHYS_BASE
    visws_get_smp_config() is nop call.
    default_get_smp_config/check_physptr/smp_read_mpc is not called in the path.
    So smp_register_lapic_address() is not called, and lapic is not mapped.


    in arch/x86/kernel/mpparse.c
    if mpf->feature1 != 0, it will go through contruct_default_ISA_mptable instead
    of check_phystr path, so smp_register_lapic_address is not called.

    Those pathes all have smp_found_config set.

    So need to remove !smp_found_config checking
