[Bjorn Helgaas]

The ia64 kernel patch for Linux 2.4.22 is available here:

    ftp://ftp.kernel.org/pub/linux/kernel/ports/ia64/v2.4/linux-2.4.22-ia64-030909.diff.gz

The current 2.4-based ia64 tree is also available as a BitKeeper
repository.  You can browse the changelog and the source files with a
normal browser at:

Hi Bjorn,

For NUMA configuration, we need the attached patch which is
the same fix as 2.6.  I confirmed both the DIG and GENERIC
kernels boot on 8-way (2-node) NEC TX7.

As for drivers/acpi/tables.c part, I think Andrew or Len is
already aware.
