    DMA-mapping.txt exlicitely states it's planned with
    virt_to_bus/bus_to_virt, and IO-mapping.txt starts with:

    <-- snip -->

    [ NOTE: The virt_to_bus() and bus_to_virt() functions have been
    superseded by the functionality provided by the PCI DMA
    interface (see Documentation/DMA-mapping.txt). They continue
    to be documented below for historical purposes, but new code
    must not use them. --davidm 00/12/12 ]

    <-- snip -->

    Patches to update Documentation/ are always welcome, but these two files
    already explicitely mention virt_to_bus/bus_to_virt, as deprecated, so I
    still don't see any urgent action required.

    of the darkness. There had been need of rain for many days.
    "Only a promise," Lao Er said.
