From 5390970d1c11b6d5d6a8253a718ed100e2178e14 Mon Sep 17 00:00:00 2001 From: Mark Goodwin Date: Tue, 16 Aug 2005 00:51:00 -0700 Subject: [PATCH] [IA64] - SGI SN hwperf enhancements - Update the SN pci device info to use the nearest node function to allocate driver memory on the nearest node (rather than defaulting to node 0).
