	  On some architectures there is currently no way for the boot loader

	  here.

	  This option will enable prompting for a variety of advanced kernel
	  configuration options.  These options can cause the kernel to not
	  work if they are set incorrectly, but can be used to optimize certain
	  aspects of kernel memory management.

	  Unless you know what you are doing, say N here.

	  This option allows you to set the base address of the kernel virtual
	  area used to map high memory pages.  This can be useful in
	  optimizing the layout of kernel virtual memory.

	  Say N here unless you know what you are doing.

	  This option allows you to set the maximum amount of memory which
	  will be used as "low memory", that is, memory which the kernel can
	  access directly, without having to set up a kernel virtual mapping.
	  This can be useful in optimizing the layout of kernel virtual

	help
	  This option allows you to set the kernel virtual address at which
	  the kernel will map low memory (the kernel image will be linked at
	  this address).  This can be useful in optimizing the virtual memory
	  layout of the system.

	  Say N here unless you know what you are doing.
