      ARM: DMA coherent allocator: align remapped addresses · 5bc23d32
      Russell King authored
      The DMA coherent remap area is used to provide an uncached mapping
      of memory for coherency with DMA engines.  Currently, we look for
      any free hole which our allocation will fit in with page alignment.
      However, this can lead to fragmentation of the area, and allows small
      allocations to cross L1 entry boundaries.  This is undesirable as we
      want to move towards allocating sections of memory.
      Align allocations according to the size, limiting the alignment between
      the page and section sizes.
