This patch adds the following new interfaces for I/O xAPIC
hotplug. The implementation of these interfaces depends on each
architecture.
o int acpi_register_ioapic(acpi_handle handle, u64 phys_addr,
u32 gsi_base);
This new interface is to add a new I/O xAPIC specified by
phys_addr and gsi_base pair. phys_addr is the physical address
to which the I/O xAPIC is mapped and gsi_base is global system
interrupt base of the I/O xAPIC. acpi_register_ioapic returns
0 on success, or negative value on error.
o int acpi_unregister_ioapic(acpi_handle handle, u32 gsi_base);
This new interface is to remove a I/O xAPIC specified by
gsi_base. acpi_unregister_ioapic returns 0 on success, or
negative value on error.
