1269 Please make sure to pick the right CPU type. Linux/MIPS is not
1270 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1271 *not* work on R4000 machines and vice versa. However, since most
1272 of the supported machines have an R4000 (or similar) CPU, R4x00
1273 might be a safe bet. If the resulting kernel does not work,
1274 try to recompile with R3000.

1497 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1498 require workarounds. Without workarounds the system may hang
1499 unexpectedly. For more information please refer to the gas
1500 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1501
1502 Loongson 2F03 and later have fixed these issues and no workarounds
1503 are needed. The workarounds have no significant side effect on them
1504 but may decrease the performance of the system so this option should
1505 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1506 systems.
1507
1508 If unsure, please say Y.

2442 that may need to compute untrusted bytecode during their
2443 execution. By using pipes or other transports made available to
2444 the process as file descriptors supporting the read/write
2445 syscalls, it's possible to isolate those applications in
2446 their own address space using seccomp. Once seccomp is
2447 enabled via /proc/<pid>/seccomp, it cannot be disabled
2448 and the task is only allowed to execute a few safe syscalls
2449 defined by each seccomp mode.

2457 When this is enabled, the kernel will support use of 64-bit floating
2458 point registers with binaries using the O32 ABI along with the
2459 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2460 32-bit MIPS systems this support is at the cost of increasing the
2461 size and complexity of the compiled FPU emulator. Thus if you are
2462 running a MIPS32 system and know that none of your userland binaries
2463 will require 64-bit floating point, you may wish to reduce the size
2464 of your kernel & potentially improve FP emulation performance by
2465 saying N here.
2466
Paul Burton06e2e882014-02-14 17:55:18 +00002467 Although binutils currently supports use of this flag the details
2468 concerning its effect upon the O32 ABI in userland are still being
2469 worked on. In order to avoid userland becoming dependant upon current
2470 behaviour before the details have been finalised, this option should
2471 be considered experimental and only enabled by those working upon
2472 said details.
2473
2474 If unsure, say N.

2549 The EISA bus provided some of the features of the IBM MicroChannel
2550 bus while maintaining backward compatibility with cards made for
