This patch integrates Linux ACPI NUMA support into Xen using the ACPI
NUMA driver and most of the x86_64 NUMA structures modified slightly for
Xen.  NUMA support is always on, however, when no NUMA information is
detected (no SRAT table in ACPI tables) we fallback on emulating one
NUMA node which owns all system memory.  Xen parse numa=off, fake=x to
bypass any SRAT parsing and will carve the memory into X nodes to
emulate a NUMA system.  The infrastructure is for both 32-bit and 64-bit

To generate the patch, untar the attached tarball and execute ./numa.sh
