    Pull dma-mapping infrastructure from Christoph Hellwig:
     "This is the first pull request for the new dma-mapping subsystem
    
      In this new subsystem we'll try to properly maintain all the generic
      code related to dma-mapping, and will further consolidate arch code
      into common helpers.
    
      This pull request contains:
    
       - removal of the DMA_ERROR_CODE macro, replacing it with calls to
         ->mapping_error so that the dma_map_ops instances are more self
         contained and can be shared across architectures (me)
    
       - removal of the ->set_dma_mask method, which duplicates the
         ->dma_capable one in terms of functionality, but requires more
         duplicate code.
    
       - various updates for the coherent dma pool and related arm code
         (Vladimir)
    
       - various smaller cleanups (me)"
