This indicates that any choice of a different swiotlb pools needs to be hidden inside of ѕwiotlb. The dma mapping API already provides swiotlb the addressability requirement for the device. Similarly we already have a SWIOTLB_ANY flag that switches to a 64-bit buffer by default, which we can change to, or replace with a flag that allocates an additional buffer that is not addressing limited.
