Hi,

Here is a set of patches to support ACPI based I/O APIC hotplug. This
code consists of the following three patches.

- Add the new interfaces for I/O APIC hot-add/hot-remove. The
implementation of these interfaces depends on each architecture.

- IA64 implementation of above-mentioned interfeces for I/O APIC
hot-add/hot-remove.

- Add I/O APIC hot-add support to ACPIPHP dirver. PCI root bridge
hot-add will be fully functional with this patch. This will be
also needed to support hot-add of p2p bridge hierarchy that
contains I/O APICs. This code supports only hot-add for now.

These patches support I/O APIC hot-plug on ia64 only for now. These
are against 2.6.12-rc2-mm3.
