982 Some MIPS machines can be configured for either little or big endian
5e83d430 983 byte order. These modes require different kernels and a different

1820 The kernel memory allocator divides physically contiguous memory
1821 blocks into "zones", where each zone is a power of two number of
1822 pages. This option selects the largest power of two that the kernel
1823 keeps in the memory allocator. If you need to allocate very large
1824 blocks of physically contiguous memory, then you may need to
1825 increase this value.
1826
1827 This config option is actually maximum order plus one. For example,
1828 a value of 11 means that the largest free memory block is 2^10 pages.
1829
1830 The page size is not necessarily 4KB. Keep this in mind
1831 when choosing a value for this option.

2446 When this is enabled, the kernel will support use of 64-bit floating

2450 size and complexity of the compiled FPU emulator. Thus if you are
2451 running a MIPS32 system and know that none of your userland binaries

2453 of your kernel & potentially improve FP emulation performance by
