1490 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1492 of the supported machines have an R4000 (or similar) CPU, R4x00
1493 might be a safe bet. If the resulting kernel does not work,

1725 64-bit addressing which in turn makes the PTEs 64-bit in size.

1741 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1742 require workarounds. Without workarounds the system may hang
1743 unexpectedly. For more information please refer to the gas
1744 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1745
1746 Loongson 2F03 and later have fixed these issues and no workarounds
1747 are needed. The workarounds have no significant side effect on them
1748 but may decrease the performance of the system so this option should
1749 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1750 systems.

2710 When this is enabled, the kernel will support use of 64-bit floating
2711 point registers with binaries using the O32 ABI along with the
2712 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2713 32-bit MIPS systems this support is at the cost of increasing the
2714 size and complexity of the compiled FPU emulator. Thus if you are
2715 running a MIPS32 system and know that none of your userland binaries
2716 will require 64-bit floating point, you may wish to reduce the size
2717 of your kernel & potentially improve FP emulation performance by
