    scatterlist: allow limited chaining without ARCH_HAS_SG_CHAIN · 10c95ed9
    Christoph Hellwig authored
    There are a couple of uses of struct scatterlist that never go to
    the dma_map_sg() helper and thus don't care about ARCH_HAS_SG_CHAIN
    which indicates that we can map chained S/G list.
    The most important one is the crypto code, which currently has
    to open code a few helpers to always allow chaining.  This patch
    removes a few #ifdef ARCH_HAS_SG_CHAIN statements so that we can
    switch the crypto code to these common helpers.
