  33. help
  34. The C6X function call instruction has a limited range of +/- 2MiB.
  35. This is sufficient for most kernels, but some kernel configurations
  36. with lots of compiled-in functionality may require a larger range
  37. for function calls. Use this option to have the compiler generate
  38. function calls with 32-bit range. This will make the kernel both
  39. larger and slower.
  40. If unsure, say N.

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

  60. Set this to have arguments from the default kernel command string
  61. override those passed by the boot loader.
  62. config CPU_BIG_ENDIAN
  63. bool "Build big-endian kernel"
  64. default n
  65. help
  66. Say Y if you plan on running a kernel in big-endian mode.
  67. Note that your board must be properly built and your board
  68. port must properly enable any big-endian related features
  69. of your chipset/board/processor.
  70. config FORCE_MAX_ZONEORDER
  71. int "Maximum zone order"
  72. default "13"
  73. help
  74. The kernel memory allocator divides physically contiguous memory
  75. blocks into "zones", where each zone is a power of two number of
  76. pages. This option selects the largest power of two that the kernel
  77. keeps in the memory allocator. If you need to allocate very large
  78. blocks of physically contiguous memory, then you may need to
  79. increase this value.
  80. This config option is actually maximum order plus one. For example,
  81. a value of 11 means that the largest free memory block is 2^10 pages.

  109. Usually the pointer transfer from user space is checked to see if its
  110. address is in the kernel space.
  111. Say N here to disable that check to improve the performance.
