Yup. I suspect a lot of people who are doing _testing_ enable that. If you're unhappy with my patch (the get_order one which shouldn't affect that many caches anyway), any suggestions how to fix this up? It seems that the wireless stack at least does quite a few kmalloc(4096) allocations.
We can probably switch back to page allocator pass-through in the near future (when Mel's patches are in) but we need a fix for -stable.
