2222 The kernel memory allocator divides physically contiguous memory
2223 blocks into "zones", where each zone is a power of two number of
2224 pages. This option selects the largest power of two that the kernel
2225 keeps in the memory allocator. If you need to allocate very large
2226 blocks of physically contiguous memory, then you may need to
2227 increase this value.
2228
2229 This config option is actually maximum order plus one. For example,
2230 a value of 11 means that the largest free memory block is 2^10 pages.

2946 When this is enabled, the kernel will support use of 64-bit floating
2947 point registers with binaries using the O32 ABI along with the
2948 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2949 32-bit MIPS systems this support is at the cost of increasing the
2950 size and complexity of the compiled FPU emulator. Thus if you are
2951 running a MIPS32 system and know that none of your userland binaries
2952 will require 64-bit floating point, you may wish to reduce the size
2953 of your kernel & potentially improve FP emulation performance by
2954 saying N here.
