To fix this, each LAPIC/X2APIC entry from MADT table needs to be
handled at the same time when processing it, thus adding
acpi_subtable_proc structure which stores
() ACPI table id
() handler that processes table
() counter how many items has been processed and passing it to
acpi_table_parse_entries().

Why can't you leave the parsing code as is and create ApicId sorted list while parsing LAPIC/X2APIC? You could call acpi_register_lapic() after all... Do I miss something ?

Just to make sure I understand correctly - you suggest to replace calls to acpi_register_lapic() with a code that builds an APIC ID list while parsing LAPIC/X2APIC, and after parsing is done,
go thru the list and call acpi_register_lapic() on each APIC ID, correct?


Yes, does it work for you?
