I also have a problem with setup_ioapic_ids_from_mpc(). I opt for 0xFF as
max io_apic phys_id (and leave it alone!), because even though we have fewer
IO-APICs than that, I'd like to keep the actual numbers from MP table or
ACPI, because all APIC and IO-APIC id's on ES7000 are 8 bit, unique, and
meaningful (used as a bitmaps) when I have to implement CPU, PCI hot plug
and dynamic partitioning (I hate to think of possible confusing tables and
dependencies I will have to maintain otherwise...).
Could this routine be made with alternative architecturally private path (as
a hook or with a hook inside)?
Thanks,
