1721 help
1722 Choose this option if you want to enable the Extended Physical
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.

2672 Generate crash dump after being started by kexec.
2673 This should be normally only set in special crash dump kernels
2674 which are loaded in the main kernel with kexec-tools into
2675 a specially reserved region and then later executed after
2676 a crash by kdump/kexec. The crash dump kernel must be compiled
2677 to a memory address not used by the main kernel or firmware using
2678 PHYSICAL_START.

2686 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2687 If you plan to use kernel for capturing the crash dump change
2688 this value to start of the reserved region (the "X" value as
2689 specified in the "crashkernel=YM@XM" command line boot parameter
2690 passed to the panic-ed kernel).

2696 help
2697 This kernel feature is useful for number crunching applications
2698 that may need to compute untrusted bytecode during their
2699 execution. By using pipes or other transports made available to
2700 the process as file descriptors supporting the read/write
2701 syscalls, it's possible to isolate those applications in
2702 their own address space using seccomp. Once seccomp is
2703 enabled via /proc/<pid>/seccomp, it cannot be disabled
2704 and the task is only allowed to execute a few safe syscalls
2705 defined by each seccomp mode.

2713 When this is enabled, the kernel will support use of 64-bit floating
2714 point registers with binaries using the O32 ABI along with the
2715 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2716 32-bit MIPS systems this support is at the cost of increasing the
2717 size and complexity of the compiled FPU emulator. Thus if you are
2718 running a MIPS32 system and know that none of your userland binaries
2719 will require 64-bit floating point, you may wish to reduce the size
2720 of your kernel & potentially improve FP emulation performance by
2721 saying N here.

2723 Although binutils currently supports use of this flag the details
2724 concerning its effect upon the O32 ABI in userland are still being
2725 worked on. In order to avoid userland becoming dependant upon current
2726 behaviour before the details have been finalised, this option should
2727 be considered experimental and only enabled by those working upon
2728 said details.
