327 DMA mapping framework by default aligns all buffers to the smallest
329 size. This works well for buffers up to a few hundreds kilobytes, but
330 for larger buffers it just a memory waste. With this parameter you can
331 specify the maximum PAGE_SIZE order for contiguous buffers. Larger
332 buffers will be aligned only to this specified order. The order is
336 of 8 means that the buffers will be aligned up to 1MiB only.
