[IA64] Cleanup use of various #defines related to nodes
Some of the SN code & #defines related to compact nodes & IO discovery have gotten stale over the years. This patch attempts to clean them up. Some of the various SN MAX_xxx #defines were also unclear & misused. The primary changes are: - use MAX_NUMNODES. This is the generic linux #define for the number of nodes that are known to the generic kernel. Arrays & loops for constructs that are 1:1 with linux-defined nodes should use the linux #define - not an SN equivalent. - use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the number of nodes in the SSI system. Compact nodes are a hack to get around the IA64 architectural limit of 256 nodes. Large SGI systems have more than 256 nodes. When we upgrade to ACPI3.0, I _hope_ that all nodes will be real nodes that are known to the generic kernel. That will allow us to delete the notion of "compact nodes". - add MAX_NUMALINK_NODES for the total number of nodes that are in the numalink domain - all partitions. - simplified (understandable) scan_for_ionodes() - small amount of cleanup related to cnodes Signed-off-by: Jack Steiner <steiner@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
