1305 Please make sure to pick the right CPU type. Linux/MIPS is not
1306 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1307 *not* work on R4000 machines and vice versa. However, since most
1308 of the supported machines have an R4000 (or similar) CPU, R4x00
1309 might be a safe bet. If the resulting kernel does not work,
1310 try to recompile with R3000.

1528 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1529 require workarounds. Without workarounds the system may hang
1530 unexpectedly. For more information please refer to the gas
1531 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1532
1533 Loongson 2F03 and later have fixed these issues and no workarounds
1534 are needed. The workarounds have no significant side effect on them
1535 but may decrease the performance of the system so this option should
1536 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1537 systems.

2439 the process as file descriptors supporting the read/write
2440 syscalls, it's possible to isolate those applications in
2441 their own address space using seccomp. Once seccomp is
2442 enabled via /proc/<pid>/seccomp, it cannot be disabled
2443 and the task is only allowed to execute a few safe syscalls

2452 When this is enabled, the kernel will support use of 64-bit floating
2453 point registers with binaries using the O32 ABI along with the
2454 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2455 32-bit MIPS systems this support is at the cost of increasing the
2456 size and complexity of the compiled FPU emulator. Thus if you are
2457 running a MIPS32 system and know that none of your userland binaries
2458 will require 64-bit floating point, you may wish to reduce the size
2459 of your kernel & potentially improve FP emulation performance by
2460 saying N here.
2461
Paul Burton06e2e882014-02-14 17:55:18 +00002462 Although binutils currently supports use of this flag the details
2463 concerning its effect upon the O32 ABI in userland are still being
2464 worked on. In order to avoid userland becoming dependant upon current
2465 behaviour before the details have been finalised, this option should
2466 be considered experimental and only enabled by those working upon
2467 said details.
2468
2469 If unsure, say N.
