That's i386 legacy, later supported by other platforms using a similar memory model -- starting at 0, mostly contiguous and only two DMA zones for ISA and 32-bit PCI respectively, both starting at 0. Remember, most people working on Linux only have an i386 PC. If you have something very different, you need to write code to support it yourself. If you do it well enough, it'll be gladly accepted.
