discontig 20020809-split file released: 03_discontig-krel-krep-v2.diff
Changed pxm_to_nid_map and nid_to_pxm_map declarations in arch/ia64/kernel/acpi.c. Changed phys_node_map initialization. Now done in discontig.c. Changed arch/ia64/kernel/acpi.c to remove references to DISCONTIG-related macros and types.

discontig 20020807-split file released: 01_discontig-acpi-numa.diff
The main change: the previous core part was splitted, the ACPI initialization was changed into arch-dependent and -independent parts. 01_discontig-acpi-numa.diff : required, provides ACPI initialization of NUMA specific variables. 02_discontig-core.diff : core part providing discontigmem functionality 03_discontig-krel-krep.diff : optional part of discontigmem, provides kernel relocation and replication. Required on SGI SN. You can pply additionally one of the zonelist patches and the discontig-proc_info patch from the previous release.
