976 Some MIPS machines can be configured for either little or big endian
5e83d430 977 byte order. These modes require different kernels and a different
3cb2fccc 978 Linux distribution. In general there is one preferred byteorder for a

1501 Loongson 2F03 and later have fixed these issues and no workarounds
1502 are needed. The workarounds have no significant side effect on them
1503 but may decrease the performance of the system so this option should

1830 The kernel memory allocator divides physically contiguous memory
1831 blocks into "zones", where each zone is a power of two number of
1832 pages. This option selects the largest power of two that the kernel
1833 keeps in the memory allocator. If you need to allocate very large
1834 blocks of physically contiguous memory, then you may need to
1835 increase this value.
1836
1837 This config option is actually maximum order plus one. For example,
1838 a value of 11 means that the largest free memory block is 2^10 pages.
1839
1840 The page size is not necessarily 4KB. Keep this in mind
1841 when choosing a value for this option.

2456 When this is enabled, the kernel will support use of 64-bit floating
2457 point registers with binaries using the O32 ABI along with the
2458 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2459 32-bit MIPS systems this support is at the cost of increasing the
2460 size and complexity of the compiled FPU emulator. Thus if you are
2461 running a MIPS32 system and know that none of your userland binaries

2463 of your kernel & potentially improve FP emulation performance by
