From 24ee0a6d7b0a52b140c880aae24c255de3b4a9a1 Mon Sep 17 00:00:00 2001 From: Jack Steiner Date: Mon, 12 Sep 2005 12:15:43 -0500 Subject: [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 Signed-off-by: Tony Luck --- arch/ia64/sn/kernel/xpc_partition.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/ia64/sn/kernel/xpc_partition.c') diff --git a/arch/ia64/sn/kernel/xpc_partition.c b/arch/ia64/sn/kernel/xpc_partition.c index 578265e..72ef330 100644 --- a/arch/ia64/sn/kernel/xpc_partition.c +++ b/arch/ia64/sn/kernel/xpc_partition.c @@ -44,7 +44,7 @@ static u64 xpc_sh2_IPI_access3; /* original protection values for each node */ -u64 xpc_prot_vec[MAX_COMPACT_NODES]; +u64 xpc_prot_vec[MAX_NUMNODES]; /* this partition's reserved page */ -- cgit v1.1
