45 bool "Build a big kernel"
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

63 bool "Default bootloader kernel arguments"
66 string "Kernel command line"
67 depends on CMDLINE_BOOL
68 default "console=ttyS0,57600"
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
76 bool "Force default kernel command string"
77 depends on CMDLINE_BOOL
80 Set this to have arguments from the default kernel command string
81 override those passed by the boot loader.
84 bool "Build big-endian kernel"
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.
92 config FORCE_MAX_ZONEORDER
93 int "Maximum zone order"
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
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.
158 Say N here to disable that check to improve the performance.
