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

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

  79 config CPU_BIG_ENDIAN

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

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