1733 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1734 require workarounds. Without workarounds the system may hang
1735 unexpectedly. For more information please refer to the gas
1736 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1737
1738 Loongson 2F03 and later have fixed these issues and no workarounds
1739 are needed. The workarounds have no significant side effect on them
1740 but may decrease the performance of the system so this option should
1741 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1742 systems.
1743
1744 If unsure, please say Y.

2688 This kernel feature is useful for number crunching applications
2689 that may need to compute untrusted bytecode during their
2690 execution. By using pipes or other transports made available to
2691 the process as file descriptors supporting the read/write
2692 syscalls, it's possible to isolate those applications in
2693 their own address space using seccomp. Once seccomp is
2694 enabled via /proc/<pid>/seccomp, it cannot be disabled
2695 and the task is only allowed to execute a few safe syscalls
2696 defined by each seccomp mode.

2704 When this is enabled, the kernel will support use of 64-bit floating
2705 point registers with binaries using the O32 ABI along with the
2706 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2707 32-bit MIPS systems this support is at the cost of increasing the
2708 size and complexity of the compiled FPU emulator. Thus if you are
2709 running a MIPS32 system and know that none of your userland binaries
2710 will require 64-bit floating point, you may wish to reduce the size
2711 of your kernel & potentially improve FP emulation performance by
2712 saying N here.

2714 Although binutils currently supports use of this flag the details
2715 concerning its effect upon the O32 ABI in userland are still being
2716 worked on. In order to avoid userland becoming dependant upon current
2717 behaviour before the details have been finalised, this option should
2718 be considered experimental and only enabled by those working upon
2719 said details.
