1542 Loongson 2F03 and later have fixed these issues and no workarounds
1543 are needed. The workarounds have no significant side effect on them
1544 but may decrease the performance of the system so this option should

2465 When this is enabled, the kernel will support use of 64-bit floating

2467 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2468 32-bit MIPS systems this support is at the cost of increasing the
2469 size and complexity of the compiled FPU emulator. Thus if you are
2470 running a MIPS32 system and know that none of your userland binaries

2472 of your kernel & potentially improve FP emulation performance by
