1731 help
1732 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1733 require workarounds. Without workarounds the system may hang
1734 unexpectedly. For more information please refer to the gas
1735 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1736
1737 Loongson 2F03 and later have fixed these issues and no workarounds
1738 are needed. The workarounds have no significant side effect on them
1739 but may decrease the performance of the system so this option should
1740 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1741 systems.
1742
1743 If unsure, please say Y.

2676 If you plan to use kernel for capturing the crash dump change
2677 this value to start of the reserved region (the "X" value as
2678 specified in the "crashkernel=YM@XM" command line boot parameter

2685 help
2686 This kernel feature is useful for number crunching applications
2687 that may need to compute untrusted bytecode during their
2688 execution. By using pipes or other transports made available to
2689 the process as file descriptors supporting the read/write
2690 syscalls, it's possible to isolate those applications in
2691 their own address space using seccomp. Once seccomp is
2692 enabled via /proc/<pid>/seccomp, it cannot be disabled
2693 and the task is only allowed to execute a few safe syscalls
2694 defined by each seccomp mode.

2701 help
2702 When this is enabled, the kernel will support use of 64-bit floating
2703 point registers with binaries using the O32 ABI along with the
2704 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2705 32-bit MIPS systems this support is at the cost of increasing the
2706 size and complexity of the compiled FPU emulator. Thus if you are
2707 running a MIPS32 system and know that none of your userland binaries
2708 will require 64-bit floating point, you may wish to reduce the size
2709 of your kernel & potentially improve FP emulation performance by
2710 saying N here.

2712 Although binutils currently supports use of this flag the details
2713 concerning its effect upon the O32 ABI in userland are still being
2714 worked on. In order to avoid userland becoming dependant upon current
2715 behaviour before the details have been finalised, this option should
2716 be considered experimental and only enabled by those working upon
2717 said details.
