  dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING for remapped allocations (2019-01-05 08:28:29 +0100)

----------------------------------------------------------------
dma-mapping fixes for Linux 4.21-rc1

Fix various regressions introduced in this cycles:

 - fix dma-debug tracking for the map_page / map_single consolidatation
 - properly stub out DMA mapping symbols for !HAS_DMA builds to avoid
   link failures
 - fix AMD Gart direct mappings
 - setup the dma address for no kernel mappings using the remap
   allocator

----------------------------------------------------------------
Christoph Hellwig (7):
      dma-mapping: implement dma_map_single_attrs using dma_map_page_attrs
      dma-mapping: implement dmam_alloc_coherent using dmam_alloc_attrs
      dma-mapping: remove dmam_{declare,release}_coherent_memory
      dma-mapping: properly stub out the DMA API for !CONFIG_HAS_DMA
      dma-mapping: remove a few unused exports
      x86/amd_gart: fix unmapping of non-GART mappings
      dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING for remapped allocations
