1561 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1564 might be a safe bet. If the resulting kernel does not work,

2162 level of page tables is added which imposes both a memory

2485 increased security at both hardware and software level for
2486 smartcards. Enabling this option will allow proper use of the

2955 When this is enabled, the kernel will support use of 64-bit floating
2956 point registers with binaries using the O32 ABI along with the
2957 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2958 32-bit MIPS systems this support is at the cost of increasing the
2959 size and complexity of the compiled FPU emulator. Thus if you are
2960 running a MIPS32 system and know that none of your userland binaries
2961 will require 64-bit floating point, you may wish to reduce the size
2962 of your kernel & potentially improve FP emulation performance by
