1720 benefit is to increase physical addressing equal to or greater
1721 than 40 bits. Note that this has the side effect of turning on
1722 64-bit addressing which in turn makes the PTEs 64-bit in size.
1723 If unsure, say 'N' here.

1738 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1739 require workarounds. Without workarounds the system may hang
1740 unexpectedly. For more information please refer to the gas
1741 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1742
1743 Loongson 2F03 and later have fixed these issues and no workarounds
1744 are needed. The workarounds have no significant side effect on them
1745 but may decrease the performance of the system so this option should
1746 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1747 systems.
1748
1749 If unsure, please say Y.

2691 This kernel feature is useful for number crunching applications
2692 that may need to compute untrusted bytecode during their
2693 execution. By using pipes or other transports made available to
2694 the process as file descriptors supporting the read/write
2695 syscalls, it's possible to isolate those applications in
2696 their own address space using seccomp. Once seccomp is
2697 enabled via /proc/<pid>/seccomp, it cannot be disabled
2698 and the task is only allowed to execute a few safe syscalls
2699 defined by each seccomp mode.

2706 help
2707 When this is enabled, the kernel will support use of 64-bit floating
2708 point registers with binaries using the O32 ABI along with the
2709 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2710 32-bit MIPS systems this support is at the cost of increasing the
2711 size and complexity of the compiled FPU emulator. Thus if you are
2712 running a MIPS32 system and know that none of your userland binaries
2713 will require 64-bit floating point, you may wish to reduce the size
2714 of your kernel & potentially improve FP emulation performance by
2715 saying N here.

2717 Although binutils currently supports use of this flag the details
2718 concerning its effect upon the O32 ABI in userland are still being
2719 worked on. In order to avoid userland becoming dependant upon current
2720 behaviour before the details have been finalised, this option should
2721 be considered experimental and only enabled by those working upon
2722 said details.
