1563 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1564 *not* work on R4000 machines and vice versa. However, since most
1565 of the supported machines have an R4000 (or similar) CPU, R4x00
1566 might be a safe bet. If the resulting kernel does not work,

2155 level of page tables is added which imposes both a memory

2224 The kernel memory allocator divides physically contiguous memory
2225 blocks into "zones", where each zone is a power of two number of
2226 pages. This option selects the largest power of two that the kernel
2227 keeps in the memory allocator. If you need to allocate very large
2228 blocks of physically contiguous memory, then you may need to
2229 increase this value.
2230
2231 This config option is actually maximum order plus one. For example,
2232 a value of 11 means that the largest free memory block is 2^10 pages.

2235 when choosing a value for this option.

2477 SmartMIPS is a extension of the MIPS32 architecture aimed at
2478 increased security at both hardware and software level for
2479 smartcards. Enabling this option will allow proper use of the
2480 SmartMIPS instructions by Linux applications. However a kernel with
2481 this option will not work on a MIPS core without SmartMIPS core. If
2482 you don't know you probably don't have SmartMIPS and should say N
2483 here.

2948 When this is enabled, the kernel will support use of 64-bit floating
2949 point registers with binaries using the O32 ABI along with the
2950 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2951 32-bit MIPS systems this support is at the cost of increasing the
2952 size and complexity of the compiled FPU emulator. Thus if you are
2953 running a MIPS32 system and know that none of your userland binaries
2954 will require 64-bit floating point, you may wish to reduce the size
2955 of your kernel & potentially improve FP emulation performance by
2956 saying N here.
