[IA64] hotplug/ia64: SN Hotplug Driver - SN Hotplug Driver code
This patch is the SGI hotplug driver and additional changes required for the driver. These modifications include changes to the SN io_init.c code for memory management, the inclusion of new SAL calls to enable and disable PCI slots, and a hotplug-style driver.
