1848 The kernel memory allocator divides physically contiguous memory
1849 blocks into "zones", where each zone is a power of two number of
1850 pages. This option selects the largest power of two that the kernel
1851 keeps in the memory allocator. If you need to allocate very large
1852 blocks of physically contiguous memory, then you may need to
1853 increase this value.
1854
1855 This config option is actually maximum order plus one. For example,
1856 a value of 11 means that the largest free memory block is 2^10 pages.

2432 When this is enabled, the kernel will support use of 64-bit floating
2433 point registers with binaries using the O32 ABI along with the
2434 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2435 32-bit MIPS systems this support is at the cost of increasing the
2436 size and complexity of the compiled FPU emulator. Thus if you are
2437 running a MIPS32 system and know that none of your userland binaries
2438 will require 64-bit floating point, you may wish to reduce the size
2439 of your kernel & potentially improve FP emulation performance by
