Jack Steiner	24ee0a6d7b	[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>	20 years ago

[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

Linux-2.6.12-rc2

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!
