1822 The kernel memory allocator divides physically contiguous memory
1823 blocks into "zones", where each zone is a power of two number of
1824 pages. This option selects the largest power of two that the kernel
1825 keeps in the memory allocator. If you need to allocate very large
1826 blocks of physically contiguous memory, then you may need to
1827 increase this value.
1828
1829 This config option is actually maximum order plus one. For example,
1830 a value of 11 means that the largest free memory block is 2^10 pages.
1831
1832 The page size is not necessarily 4KB. Keep this in mind
1833 when choosing a value for this option.

2448 When this is enabled, the kernel will support use of 64-bit floating

2452 size and complexity of the compiled FPU emulator. Thus if you are
2453 running a MIPS32 system and know that none of your userland binaries

2455 of your kernel & potentially improve FP emulation performance by
