1722 benefit is to increase physical addressing equal to or greater
1723 than 40 bits. Note that this has the side effect of turning on
1724 64-bit addressing which in turn makes the PTEs 64-bit in size.
1725 If unsure, say 'N' here.

1740 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1741 require workarounds. Without workarounds the system may hang
1742 unexpectedly. For more information please refer to the gas
1743 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1744
1745 Loongson 2F03 and later have fixed these issues and no workarounds
1746 are needed. The workarounds have no significant side effect on them
1747 but may decrease the performance of the system so this option should
1748 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1749 systems.
1750
1751 If unsure, please say Y.

2693 This kernel feature is useful for number crunching applications
2694 that may need to compute untrusted bytecode during their
2695 execution. By using pipes or other transports made available to
2696 the process as file descriptors supporting the read/write
2697 syscalls, it's possible to isolate those applications in
2698 their own address space using seccomp. Once seccomp is
2699 enabled via /proc/<pid>/seccomp, it cannot be disabled
2700 and the task is only allowed to execute a few safe syscalls
2701 defined by each seccomp mode.

2709 When this is enabled, the kernel will support use of 64-bit floating
2710 point registers with binaries using the O32 ABI along with the
2711 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2712 32-bit MIPS systems this support is at the cost of increasing the
2713 size and complexity of the compiled FPU emulator. Thus if you are
2714 running a MIPS32 system and know that none of your userland binaries
2715 will require 64-bit floating point, you may wish to reduce the size
2716 of your kernel & potentially improve FP emulation performance by
2717 saying N here.

2719 Although binutils currently supports use of this flag the details
2720 concerning its effect upon the O32 ABI in userland are still being
2721 worked on. In order to avoid userland becoming dependant upon current
2722 behaviour before the details have been finalised, this option should
2723 be considered experimental and only enabled by those working upon
2724 said details.
