40config C6X_BIG_KERNEL
41 bool "Build a big kernel"
42 help
43 The C6X function call instruction has a limited range of +/- 2MiB.
44 This is sufficient for most kernels, but some kernel configurations
45 with lots of compiled-in functionality may require a larger range
46 for function calls. Use this option to have the compiler generate
47 function calls with 32-bit range. This will make the kernel both
48 larger and slower.
49
50 If unsure, say N.

66 On some architectures there is currently no way for the boot loader
67 to pass arguments to the kernel. For these architectures, you should
68 supply some command-line options at build time by entering them
69 here.

79config CPU_BIG_ENDIAN
80 bool "Build big-endian kernel"
81 default n
82 help
83 Say Y if you plan on running a kernel in big-endian mode.
84 Note that your board must be properly built and your board
85 port must properly enable any big-endian related features
86 of your chipset/board/processor.

88config FORCE_MAX_ZONEORDER
89 int "Maximum zone order"
90 default "13"
91 help
92 The kernel memory allocator divides physically contiguous memory
93 blocks into "zones", where each zone is a power of two number of
94 pages. This option selects the largest power of two that the kernel
95 keeps in the memory allocator. If you need to allocate very large
96 blocks of physically contiguous memory, then you may need to
97 increase this value.
98
99 This config option is actually maximum order plus one. For example,
100 a value of 11 means that the largest free memory block is 2^10 pages.

147 Usually the pointer transfer from user space is checked to see if its
148 address is in the kernel space.
149
150 Say N here to disable that check to improve the performance.
