• efa70f2fd   dma-mapping: add a new dma_alloc_pages API ... Browse Code »

  This API is the equivalent of alloc_pages, except that the returned memory
  is guaranteed to be DMA addressable by the passed in device. The
  implementation will also be used to provide a more sensible replacement
  for DMA_ATTR_NON_CONSISTENT flag.

  Additionally dma_alloc_noncoherent is switched over to use dma_alloc_pages
  as its backend.

  Move those files to the core-api, where they belong, renaming
