This patch set primarily updates the Linux kernel to support the next
generation SGI Ultraviolet system, UV4. This architecture change is a
larger incremental change than previous UV updates because of a major
change to the addressing scheme. Previous UV architectures used a fixed
address width

that might not be fully defined for all arches, as long as they do not
reference them on the unsupported arches.

Use no-op messages in place of cross-partition interrupts when nacking a
put message in the GRU. This allows us to remove MMR's as a destination
from the GRU driver.

This patch set primarily updates the Linux kernel to support the next
generation SGI Ultraviolet system, UV4. This architecture change is a
larger incremental change than previous UV updates because of a major
change to the addressing scheme. Previous UV architectures used a fixed
address width

The major portion of the hub info is common to all cpus on that hub.
This is step one of moving the per cpu hub info to a per node hub info
struct. This patch creates the small per cpu info struct that will
contain only information specific to each CPU.
