1740 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1741 require workarounds. Without workarounds the system may hang
1742 unexpectedly. For more information please refer to the gas
1743 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1744
1745 Loongson 2F03 and later have fixed these issues and no workarounds
1746 are needed. The workarounds have no significant side effect on them
1747 but may decrease the performance of the system so this option should
1748 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1749 systems.

2710 point registers with binaries using the O32 ABI along with the
2711 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2712 32-bit MIPS systems this support is at the cost of increasing the
2713 size and complexity of the compiled FPU emulator. Thus if you are
2714 running a MIPS32 system and know that none of your userland binaries
2715 will require 64-bit floating point, you may wish to reduce the size
2716 of your kernel & potentially improve FP emulation performance by
