Linus Torvalds f72e24a124 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)
