      asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.h · 204f3a04
      FUJITA Tomonori authored
      This is the first half of the attempt to use asm-generic/scatterlist.h
      on every architecture.
      There are only two ways to define scatterlist structure. So it's easy
      to convert every architecture to use asm-generic/scatterlist.h.
      This patch:
      The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work
      for powerpc.  This lets architectures defin ISA_DMA_THRESHOLD.
      Hopefully, we can remove ISA_DMA_THRESHOLD in the future; we can do better
      to decide if the bouncing is necessary or not.
