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

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

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

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