  164. Select the kernel logical page size. Increasing the page size
  165. will reduce software overhead at each page boundary, allow
  166. hardware prefetch mechanisms to be more effective, and allow
  167. larger dma transfers increasing IO efficiency and reducing
  168. overhead. However the utilization of memory will increase.
