To preserve the x86 behavior.And combined with patch 10/22 of the SWIOTLB refactoring, this means SWIOTLB allocations will also end up NUMA-aware, right? Great, that's what we want on arm64 too :)
Well, only for swiotlb allocations that can be satisfied by dma_direct_alloc. If we actually have to fall back to the swiotlb buffers there is not node affinity yet.
