1559 Loongson 2F03 and later have fixed these issues and no workarounds
1560 are needed. The workarounds have no significant side effect on them
1561 but may decrease the performance of the system so this option should

2475 When this is enabled, the kernel will support use of 64-bit floating
2476 point registers with binaries using the O32 ABI along with the
2477 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2478 32-bit MIPS systems this support is at the cost of increasing the
2479 size and complexity of the compiled FPU emulator. Thus if you are
2480 running a MIPS32 system and know that none of your userland binaries
2481 will require 64-bit floating point, you may wish to reduce the size
2482 of your kernel & potentially improve FP emulation performance by
