    Update DMA-mapping documentation · d1482f40
    Matthew Wilcox authored
    A couple of updates haven't considered whether the documentation makes
    sense as a whole any more.  Three changes here:
    
     - Remove the reference to the "DAC Addressing for Address Space Hungry
       Devices" section which was deleted by Jan Beulich.
     - Remove the comment about DMA_24BIT_MASK which became obsolete when
       Tobias Klauser changed the code to actually use DMA_24BIT_MASK.
     - Remove the section "64-bit DMA and DAC cycle support" since it's
       fully covered above, and contains a reference to the section deleted
       by Jan.
