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

64 bool "Default bootloader kernel arguments"
67 string "Kernel command line"
68 depends on CMDLINE_BOOL
69 default "console=ttyS0,57600"
71 On some architectures there is currently no way for the boot loader
72 to pass arguments to the kernel. For these architectures, you should
73 supply some command-line options at build time by entering them
77 bool "Force default kernel command string"
78 depends on CMDLINE_BOOL
81 Set this to have arguments from the default kernel command string
82 override those passed by the boot loader.
85 bool "Build big-endian kernel"
88 Say Y if you plan on running a kernel in big-endian mode.
89 Note that your board must be properly built and your board
90 port must properly enable any big-endian related features
91 of your chipset/board/processor.
93 config FORCE_MAX_ZONEORDER
94 int "Maximum zone order"
97 The kernel memory allocator divides physically contiguous memory
98 blocks into "zones", where each zone is a power of two number of
99 pages. This option selects the largest power of two that the kernel
100 keeps in the memory allocator. If you need to allocate very large
101 blocks of physically contiguous memory, then you may need to
104 This config option is actually maximum order plus one. For example,
105 a value of 11 means that the largest free memory block is 2^10 pages.

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