  59        help
  60          The C6X function call instruction has a limited range of +/- 2MiB.
  61          This is sufficient for most kernels, but some kernel configurations
  62          with lots of compiled-in functionality may require a larger range
  63          for function calls. Use this option to have the compiler generate
  64          function calls with 32-bit range. This will make the kernel both
  65          larger and slower.
  66
  67          If unsure, say N.

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

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

 105config FORCE_MAX_ZONEORDER

 108        help
 109          The kernel memory allocator divides physically contiguous memory
 110          blocks into "zones", where each zone is a power of two number of
 111          pages.  This option selects the largest power of two that the kernel
 112          keeps in the memory allocator.  If you need to allocate very large
 113          blocks of physically contiguous memory, then you may need to
 114          increase this value.
 115
 116          This config option is actually maximum order plus one. For example,
 117          a value of 11 means that the largest free memory block is 2^10 pages.
