    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.
