978 Some MIPS machines can be configured for either little or big endian
5e83d430 979 byte order. These modes require different kernels and a different

1832 The kernel memory allocator divides physically contiguous memory
1833 blocks into "zones", where each zone is a power of two number of
1834 pages. This option selects the largest power of two that the kernel
1835 keeps in the memory allocator. If you need to allocate very large
1836 blocks of physically contiguous memory, then you may need to
1837 increase this value.
1838
1839 This config option is actually maximum order plus one. For example,
1840 a value of 11 means that the largest free memory block is 2^10 pages.
1841
1842 The page size is not necessarily 4KB. Keep this in mind
1843 when choosing a value for this option.

2463 When this is enabled, the kernel will support use of 64-bit floating
2464 point registers with binaries using the O32 ABI along with the
2465 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2466 32-bit MIPS systems this support is at the cost of increasing the
2467 size and complexity of the compiled FPU emulator. Thus if you are
2468 running a MIPS32 system and know that none of your userland binaries
2469 will require 64-bit floating point, you may wish to reduce the size
2470 of your kernel & potentially improve FP emulation performance by
