2459           Generate crash dump after being started by kexec.
2460           This should be normally only set in special crash dump kernels
2461           which are loaded in the main kernel with kexec-tools into
2462           a specially reserved region and then later executed after
2463           a crash by kdump/kexec. The crash dump kernel must be compiled
2464           to a memory address not used by the main kernel or firmware using
2465           PHYSICAL_START.
2466 
2467 config PHYSICAL_START

2473           This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2474           If you plan to use kernel for capturing the crash dump change
2475           this value to start of the reserved region (the "X" value as
2476           specified in the "crashkernel=YM@XM" command line boot parameter

2483         help
2484           This kernel feature is useful for number crunching applications
2485           that may need to compute untrusted bytecode during their
2486           execution. By using pipes or other transports made available to
2487           the process as file descriptors supporting the read/write
2488           syscalls, it's possible to isolate those applications in
2489           their own address space using seccomp. Once seccomp is
2490           enabled via /proc/<pid>/seccomp, it cannot be disabled
2491           and the task is only allowed to execute a few safe syscalls
2492           defined by each seccomp mode.

2499         help
2500           When this is enabled, the kernel will support use of 64-bit floating
2501           point registers with binaries using the O32 ABI along with the
2502           EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2503           32-bit MIPS systems this support is at the cost of increasing the
2504           size and complexity of the compiled FPU emulator. Thus if you are
2505           running a MIPS32 system and know that none of your userland binaries
2506           will require 64-bit floating point, you may wish to reduce the size
2507           of your kernel & potentially improve FP emulation performance by
2508           saying N here.
2509 
2510           Although binutils currently supports use of this flag the details
2511           concerning its effect upon the O32 ABI in userland are still being
2512           worked on. In order to avoid userland becoming dependant upon current
2513           behaviour before the details have been finalised, this option should
2514           be considered experimental and only enabled by those working upon
2515           said details.
