Are there kernel APIs for NUMA?

As NUMA-like architectures have become almost ubiqutous, even in i386 / amd64 architectures, there are potentially big performance gains to be had in enabling its supports within operating systems. New development aims to adapt the physical page allocator to be NUMA-aware.

actually, vermaden, the commit say "Initial NUMA support", not "full NUMA support". Now, if I understand correctly the current discussion on hackers@[0], NUMA supports is far from ideal.
