      treewide: Move dma_ops from struct dev_archdata into struct device · 5657933d
      Bart Van Assche authored
      Some but not all architectures provide set_dma_ops(). Move dma_ops
      from struct dev_archdata into struct device such that it becomes
      possible on all architectures to configure dma_ops per device.

      treewide: Constify most dma_map_ops structures · 5299709d
      Bart Van Assche authored
      Most dma_map_ops structures are never modified. Constify these
      structures such that these can be write-protected. This patch
      has been generated as follows:
      
      git grep -l 'struct dma_map_ops' |
        xargs -d\\n sed -i \
          -e 's/struct dma_map_ops/const struct dma_map_ops/g' \
          -e 's/const struct dma_map_ops {/struct dma_map_ops {/g' \
          -e 's/^const struct dma_map_ops;$/struct dma_map_ops;/' \
          -e 's/const const struct dma_map_ops /const struct dma_map_ops /g';
      sed -i -e 's/const \(struct dma_map_ops intel_dma_ops\)/\1/' \
        $(git grep -l 'struct dma_map_ops intel_dma_ops');
      sed -i -e 's/const \(struct dma_map_ops dma_iommu_ops\)/\1/' \
        $(git grep -l 'struct dma_map_ops' | grep ^arch/powerpc);
      sed -i -e '/^struct vmd_dev {$/,/^};$/ s/const \(struct dma_map_ops[[:blank:]]dma_ops;\)/\1/' \
             -e '/^static void vmd_setup_dma_ops/,/^}$/ s/const \(struct dma_map_ops \*dest\)/\1/' \
             -e 's/const \(struct dma_map_ops \*dest = \&vmd->dma_ops\)/\1/' \
