  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.

  78config 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.

  87config FORCE_MAX_ZONEORDER
  88        int "Maximum zone order"
  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.

 146          Usually the pointer transfer from user space is checked to see if its
 147          address is in the kernel space.
 148
 149          Say N here to disable that check to improve the performance.
