59 bool "Build a big kernel"
61 The C6X function call instruction has a limited range of +/- 2MiB.
62 This is sufficient for most kernels, but some kernel configurations
63 with lots of compiled-in functionality may require a larger range
64 for function calls. Use this option to have the compiler generate
65 function calls with 32-bit range. This will make the kernel both

77 bool "Default bootloader kernel arguments"
80 string "Kernel command line"
81 depends on CMDLINE_BOOL
82 default "console=ttyS0,57600"
84 On some architectures there is currently no way for the boot loader
85 to pass arguments to the kernel. For these architectures, you should
86 supply some command-line options at build time by entering them
90 bool "Force default kernel command string"
91 depends on CMDLINE_BOOL
94 Set this to have arguments from the default kernel command string
95 override those passed by the boot loader.
98 bool "Build big-endian kernel"
101 Say Y if you plan on running a kernel in big-endian mode.
102 Note that your board must be properly built and your board
103 port must properly enable any big-endian related features
104 of your chipset/board/processor.

107 int "Maximum zone order"
110 The kernel memory allocator divides physically contiguous memory
111 blocks into "zones", where each zone is a power of two number of
112 pages. This option selects the largest power of two that the kernel
113 keeps in the memory allocator. If you need to allocate very large
114 blocks of physically contiguous memory, then you may need to
117 This config option is actually maximum order plus one. For example,
118 a value of 11 means that the largest free memory block is 2^10 pages.

170 Usually the pointer transfer from user space is checked to see if its
171 address is in the kernel space.
