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

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

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

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