1537 Loongson 2F03 and later have fixed these issues and no workarounds
1538 are needed. The workarounds have no significant side effect on them
1539 but may decrease the performance of the system so this option should

2459 When this is enabled, the kernel will support use of 64-bit floating
2460 point registers with binaries using the O32 ABI along with the
2461 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2462 32-bit MIPS systems this support is at the cost of increasing the
2463 size and complexity of the compiled FPU emulator. Thus if you are
2464 running a MIPS32 system and know that none of your userland binaries
2465 will require 64-bit floating point, you may wish to reduce the size
2466 of your kernel & potentially improve FP emulation performance by
