794 This option supports all of the Octeon reference boards from Cavium
795 Networks. It builds a kernel that dynamically determines the Octeon
796 CPU type and supports all known board reference implementations.
797 Some of the supported boards are:
798 EBT3000
799 EBH3000
800 EBH3100
801 Thunder
802 Kodama
803 Hikari

1349 Please make sure to pick the right CPU type. Linux/MIPS is not
1350 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1351 *not* work on R4000 machines and vice versa. However, since most
1352 of the supported machines have an R4000 (or similar) CPU, R4x00
1353 might be a safe bet. If the resulting kernel does not work,
1354 try to recompile with R3000.

1577 Loongson 2F03 and later have fixed these issues and no workarounds
1578 are needed. The workarounds have no significant side effect on them
1579 but may decrease the performance of the system so this option should
1580 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1916 blocks into "zones", where each zone is a power of two number of

1918 keeps in the memory allocator. If you need to allocate very large
1919 blocks of physically contiguous memory, then you may need to
1920 increase this value.

1922 This config option is actually maximum order plus one. For example,
1923 a value of 11 means that the largest free memory block is 2^10 pages.

2500 When this is enabled, the kernel will support use of 64-bit floating
2501 point registers with binaries using the O32 ABI along with the
2502 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2503 32-bit MIPS systems this support is at the cost of increasing the
2504 size and complexity of the compiled FPU emulator. Thus if you are
2505 running a MIPS32 system and know that none of your userland binaries
2506 will require 64-bit floating point, you may wish to reduce the size
2507 of your kernel & potentially improve FP emulation performance by
2508 saying N here.

2512 worked on. In order to avoid userland becoming dependant upon current
2513 behaviour before the details have been finalised, this option should
2514 be considered experimental and only enabled by those working upon
2515 said details.
