    Because there are two distinct and separate models of port mapping/usage:

    1) A bunch of separate IO address spaces (PIO). The "mapping" is
    currently done in ata_pci_init_native_mode() and ata_pci_init_legacy_mode()

    2) One single linear address space (MMIO). The mapping is done in the
    low-level driver.

    #1 is in the library because the logic is duplicated _precisely_, across
    multiple host controllers, according to a hardware specification.

    Thus, if the mapping is done in the library core, so should the unmapping.
