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

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

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

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