The patches themselves are pretty minimal and similar to the ia64 changes (and the affected code seems like it hasn't changed in some time, beyond in the common code). I'd mostly like to get some broad-range build & boot testing. Also, is NUMA a sufficient symbol to depend, you think? I figure most of the PPC NUMA systems are the pSeries/IBM variety, which is where I've run into memoryless nodes in the first place.
