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

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

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

  92config FORCE_MAX_ZONEORDER

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

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