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

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

  78 config CPU_BIG_ENDIAN

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

  87 config FORCE_MAX_ZONEORDER

  89         default "13"
  90         help
  91           The kernel memory allocator divides physically contiguous memory
  92           blocks into "zones", where each zone is a power of two number of
  93           pages.  This option selects the largest power of two that the kernel
  94           keeps in the memory allocator.  If you need to allocate very large
  95           blocks of physically contiguous memory, then you may need to
  96           increase this value.
  97
  98           This config option is actually maximum order plus one. For example,
  99           a value of 11 means that the largest free memory block is 2^10 pages.
