1491 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1742 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1743 require workarounds. Without workarounds the system may hang
1744 unexpectedly. For more information please refer to the gas
1745 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1746
1747 Loongson 2F03 and later have fixed these issues and no workarounds
1748 are needed. The workarounds have no significant side effect on them
1749 but may decrease the performance of the system so this option should
1750 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1751 systems.

2712 point registers with binaries using the O32 ABI along with the
2713 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2714 32-bit MIPS systems this support is at the cost of increasing the
2715 size and complexity of the compiled FPU emulator. Thus if you are
2716 running a MIPS32 system and know that none of your userland binaries
2717 will require 64-bit floating point, you may wish to reduce the size
2718 of your kernel & potentially improve FP emulation performance by
