  55         help
  56           The C6X function call instruction has a limited range of +/- 2MiB.
  57           This is sufficient for most kernels, but some kernel configurations
  58           with lots of compiled-in functionality may require a larger range
  59           for function calls. Use this option to have the compiler generate
  60           function calls with 32-bit range. This will make the kernel both
  61           larger and slower.
  62
  63           If unsure, say N.

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

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

 104         help
 105           The kernel memory allocator divides physically contiguous memory
 106           blocks into "zones", where each zone is a power of two number of
 107           pages.  This option selects the largest power of two that the kernel
 108           keeps in the memory allocator.  If you need to allocate very large
 109           blocks of physically contiguous memory, then you may need to
 110           increase this value.
 111
 112           This config option is actually maximum order plus one. For example,
 113           a value of 11 means that the largest free memory block is 2^10 pages.
