58 | bool "Build a big kernel" | ||
59 | help | ||
60 | The C6X function call instruction has a limited range of +/- 2MiB. | ||
61 | This is sufficient for most kernels, but some kernel configurations | ||
62 | with lots of compiled-in functionality may require a larger range | ||
63 | for function calls. Use this option to have the compiler generate | ||
64 | function calls with 32-bit range. This will make the kernel both | ||
65 | larger and slower. | ||
66 | |||
67 | If unsure, say N. | ||

83 | On some architectures there is currently no way for the boot loader | ||

98 | default n | ||
99 | help | ||
100 | Say Y if you plan on running a kernel in big-endian mode. | ||
101 | Note that your board must be properly built and your board | ||
102 | port must properly enable any big-endian related features | ||
103 | of your chipset/board/processor. | ||

105 | config FORCE_MAX_ZONEORDER | ||
106 | int "Maximum zone order" | ||
107 | default "13" | ||
108 | help | ||
109 | The kernel memory allocator divides physically contiguous memory | ||
110 | blocks into "zones", where each zone is a power of two number of | ||
111 | pages. This option selects the largest power of two that the kernel | ||
112 | keeps in the memory allocator. If you need to allocate very large | ||
113 | blocks of physically contiguous memory, then you may need to | ||
114 | increase this value. | ||
115 | |||
116 | This config option is actually maximum order plus one. For example, | ||
117 | a value of 11 means that the largest free memory block is 2^10 pages. | ||
