- Enable K8 NUMA node topology detection. You should say Y here if
- you have a multi processor AMD K8 system. This uses an old
- method to read the NUMA configuration directly from the builtin
- Northbridge of Opteron. It is recommended to use X86_64_ACPI_NUMA
- instead, which also takes priority if both are compiled in.
