  45         help
  46           The C6X function call instruction has a limited range of +/- 2MiB.
  47           This is sufficient for most kernels, but some kernel configurations
  48           with lots of compiled-in functionality may require a larger range
  49           for function calls. Use this option to have the compiler generate
  50           function calls with 32-bit range. This will make the kernel both
  51           larger and slower.
  52
  53           If unsure, say N.

  69           On some architectures there is currently no way for the boot loader
  70           to pass arguments to the kernel. For these architectures, you should
  71           supply some command-line options at build time by entering them
  72           here.

  86           Say Y if you plan on running a kernel in big-endian mode.
  87           Note that your board must be properly built and your board
  88           port must properly enable any big-endian related features
  89           of your chipset/board/processor.

  94         help
  95           The kernel memory allocator divides physically contiguous memory
  96           blocks into "zones", where each zone is a power of two number of
  97           pages.  This option selects the largest power of two that the kernel
  98           keeps in the memory allocator.  If you need to allocate very large
  99           blocks of physically contiguous memory, then you may need to
 100           increase this value.
 101
 102           This config option is actually maximum order plus one. For example,
 103           a value of 11 means that the largest free memory block is 2^10 pages.
