 141           This is needed to be able to allocate uncachable memory regions.

 211           Select the kernel logical page size. Increasing the page size
 212           will reduce software overhead at each page boundary, allow
 213           hardware prefetch mechanisms to be more effective, and allow
 214           larger dma transfers increasing IO efficiency and reducing
 215           overhead. However the utilization of memory will increase.
 216           For example, each cached file will using a multiple of the
 217           page size to hold its contents and the difference between the
