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

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

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