 147           configuration options.  These options can cause the kernel to not
 148           work if they are set incorrectly, but can be used to optimize certain

 161           This is needed to be able to allocate uncachable memory regions.
 162           The feature requires the design to define the RAM memory controller

 185           will be used as "low memory", that is, memory which the kernel can
 186           access directly, without having to set up a kernel virtual mapping.

 202           this address).  This can be useful in optimizing the virtual memory
