Altix only patch to add fixup code that sets up
pci_controller->window. This code is a temporary
fix until ACPI support on Altix is added.
Also, corrects the usage of pci_dev->sysdata,
which had previously been used to reference
platform specific device info, to now point to
a pci_controller struct.

for memory management, the inclusion of new SAL calls to enable and disable

This patch moves header files out of the arch/ia64/sn directories and into
include/asm-ia64/sn. These files were being included by other subsystems
and should be under include/asm-ia64/sn.

This patch fixes the SN IRQ code such that cpu affinity and
Hotplug can modify IRQ values. The sn_irq_info structures are now locked
using a RCU lock mechanism to avoid lock contention in the lost interrupt
WAR code.
