1723 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1724 benefit is to increase physical addressing equal to or greater
1725 than 40 bits. Note that this has the side effect of turning on
1726 64-bit addressing which in turn makes the PTEs 64-bit in size.
1727 If unsure, say 'N' here.

1742 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1743 require workarounds. Without workarounds the system may hang
1744 unexpectedly. For more information please refer to the gas
1745 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1746
1747 Loongson 2F03 and later have fixed these issues and no workarounds
1748 are needed. The workarounds have no significant side effect on them
1749 but may decrease the performance of the system so this option should
1750 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1751 systems.
1752
1753 If unsure, please say Y.

2695 This kernel feature is useful for number crunching applications
2696 that may need to compute untrusted bytecode during their
2697 execution. By using pipes or other transports made available to
2698 the process as file descriptors supporting the read/write
2699 syscalls, it's possible to isolate those applications in
2700 their own address space using seccomp. Once seccomp is
2701 enabled via /proc/<pid>/seccomp, it cannot be disabled
2702 and the task is only allowed to execute a few safe syscalls
2703 defined by each seccomp mode.

2711 When this is enabled, the kernel will support use of 64-bit floating
2712 point registers with binaries using the O32 ABI along with the
2713 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2714 32-bit MIPS systems this support is at the cost of increasing the
2715 size and complexity of the compiled FPU emulator. Thus if you are
2716 running a MIPS32 system and know that none of your userland binaries
2717 will require 64-bit floating point, you may wish to reduce the size
2718 of your kernel & potentially improve FP emulation performance by
2719 saying N here.

2721 Although binutils currently supports use of this flag the details
2722 concerning its effect upon the O32 ABI in userland are still being
2723 worked on. In order to avoid userland becoming dependant upon current
2724 behaviour before the details have been finalised, this option should
2725 be considered experimental and only enabled by those working upon
2726 said details.
