1722 help
1723 Choose this option if you want to enable the Extended Physical
1724 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1725 benefit is to increase physical addressing equal to or greater
1726 than 40 bits. Note that this has the side effect of turning on
1727 64-bit addressing which in turn makes the PTEs 64-bit in size.
1728 If unsure, say 'N' here.

1743 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1744 require workarounds. Without workarounds the system may hang
1745 unexpectedly. For more information please refer to the gas
1746 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1747
1748 Loongson 2F03 and later have fixed these issues and no workarounds
1749 are needed. The workarounds have no significant side effect on them
1750 but may decrease the performance of the system so this option should
1751 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1752 systems.
1753
1754 If unsure, please say Y.

2712 This kernel feature is useful for number crunching applications

2714 execution. By using pipes or other transports made available to
2715 the process as file descriptors supporting the read/write
2716 syscalls, it's possible to isolate those applications in
2717 their own address space using seccomp. Once seccomp is
2718 enabled via /proc/<pid>/seccomp, it cannot be disabled

2728 When this is enabled, the kernel will support use of 64-bit floating
2729 point registers with binaries using the O32 ABI along with the
2730 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2731 32-bit MIPS systems this support is at the cost of increasing the
2732 size and complexity of the compiled FPU emulator. Thus if you are
2733 running a MIPS32 system and know that none of your userland binaries
2734 will require 64-bit floating point, you may wish to reduce the size
2735 of your kernel & potentially improve FP emulation performance by
2736 saying N here.

2738 Although binutils currently supports use of this flag the details
2739 concerning its effect upon the O32 ABI in userland are still being

2741 behaviour before the details have been finalised, this option should
2742 be considered experimental and only enabled by those working upon
2743 said details.
