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

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

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

  91config FORCE_MAX_ZONEORDER

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

 154          Usually the pointer transfer from user space is checked to see if its
 155          address is in the kernel space.
 156
 157          Say N here to disable that check to improve the performance.
