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

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

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