42config C6X_BIG_KERNEL
43 bool "Build a big kernel"
44 help
45 The C6X function call instruction has a limited range of +/- 2MiB.
46 This is sufficient for most kernels, but some kernel configurations
47 with lots of compiled-in functionality may require a larger range
48 for function calls. Use this option to have the compiler generate
49 function calls with 32-bit range. This will make the kernel both
50 larger and slower.
51
52 If unsure, say N.

67 help

69 to pass arguments to the kernel. For these architectures, you should
70 supply some command-line options at build time by entering them
71 here.

81config CPU_BIG_ENDIAN
82 bool "Build big-endian kernel"
83 default n
84 help
85 Say Y if you plan on running a kernel in big-endian mode.
86 Note that your board must be properly built and your board
87 port must properly enable any big-endian related features
88 of your chipset/board/processor.

90config FORCE_MAX_ZONEORDER
91 int "Maximum zone order"
92 default "13"
93 help
94 The kernel memory allocator divides physically contiguous memory
95 blocks into "zones", where each zone is a power of two number of
96 pages. This option selects the largest power of two that the kernel
97 keeps in the memory allocator. If you need to allocate very large
98 blocks of physically contiguous memory, then you may need to
99 increase this value.
100
101 This config option is actually maximum order plus one. For example,
102 a value of 11 means that the largest free memory block is 2^10 pages.

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