1533 Loongson 2F03 and later have fixed these issues and no workarounds
1534 are needed. The workarounds have no significant side effect on them
1535 but may decrease the performance of the system so this option should
1536 be disabled unless the kernel is intended to be run on 2F01 or 2F02

2452 When this is enabled, the kernel will support use of 64-bit floating
2453 point registers with binaries using the O32 ABI along with the
2454 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2455 32-bit MIPS systems this support is at the cost of increasing the
2456 size and complexity of the compiled FPU emulator. Thus if you are
2457 running a MIPS32 system and know that none of your userland binaries
2458 will require 64-bit floating point, you may wish to reduce the size
2459 of your kernel & potentially improve FP emulation performance by
