pcidev_info list prior to free'ing the pcidev_info struct.

Redirecting interrupts using smp_affinity on altix does not work on kernels
built with CONFIG_PCI_MSI. The problem is that move_irq() turns into a noop
if MSI is built in. This patch calls move_native_irq() instead of move_irq()
to get around that.

Altix patch to abstract irq_affinity down to the pci provider level since
different SGI hardware implements this in different ways.

Use local SHUB alias space when referencing MMRs that are known
to be node local. There is a slight performance benefit & code
simplification.

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.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
