@slm - what you say makes sense, but why does the kernel documentation (quoted in my question) say I should enable CONFIG_NUMA for core i7 ?

Since Haswell it is no longer true that NUMA is not of any use for a 'single processor' (meaning single socket) machine. Certain Haswell products feature what Intel terms the 'Cluster on Die' mode. The single socket processor has multiple memory controllers integrated and therefore multiple paths to memory, which with this feature may be treated as distinct NUMA regions, all of which encompass the one socket.
