  47         help
  48           The C6X function call instruction has a limited range of +/- 2MiB.
  49           This is sufficient for most kernels, but some kernel configurations
  50           with lots of compiled-in functionality may require a larger range
  51           for function calls. Use this option to have the compiler generate
  52           function calls with 32-bit range. This will make the kernel both
  53           larger and slower.
  54
  55           If unsure, say N.

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

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

  96         help
  97           The kernel memory allocator divides physically contiguous memory
  98           blocks into "zones", where each zone is a power of two number of
  99           pages.  This option selects the largest power of two that the kernel
 100           keeps in the memory allocator.  If you need to allocate very large
 101           blocks of physically contiguous memory, then you may need to
 102           increase this value.
 103
 104           This config option is actually maximum order plus one. For example,
 105           a value of 11 means that the largest free memory block is 2^10 pages.
