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

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

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