 119           to pass arguments to the kernel. For these architectures, you should

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

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

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