Martin,

I checked that the code for changeset 1.1292.1.3 is already present in 2.6.0 test4. 

# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
#	           ChangeSet	1.1292.1.2 -> 1.1292.1.3
#	 arch/ia64/mm/numa.c	1.1     -> 1.2

# [PATCH] ia64: paddr_to_nid fixup
# 
# Here is a small patch for paddr_to_nid().  This fix is already in 2.4
# and is used in the case where a NUMA kernel is running on a machine
# without a SRAT ACPI table.  Without this patch the node info is not
# correctly located.
