We want to stick close to Linux 2.6 code. Comparing your code with
2.6.12:
1. MAX_IO_APICS is never set to 65 or 129 in 2.6.12. Do you really
have systems with 129 IO APICs? x86_64 sets it to 128 always; i386 to
32.
2. setup_ioapic_ids_from_mpc: 2.6.12 gates this function on a genapic
hook, not an explicit CPU version check. Why the difference?
3. mp_register_ioapic/mp_register_gsi: I see no equivalent of your
changes in the 2.6.12 tree. Are they awaiting inclusion, or are they in
a 2.6.13-rc tree that I ought to be looking at?
I would like the patch closer to 2.6.12, or to know what mainline Linux
tree you based it on.
