2414 bool "Kexec system call"
2415 help
2416 kexec is a system call that implements the ability to shutdown your
2417 current kernel, and to start another kernel. It is like a reboot
2418 but it is independent of the system firmware. And like a reboot
2419 you can start any kernel with it, not just Linux.
2420
2421 The name comes from the similarity to the exec system call.
2422
2423 It is an ongoing process to be certain the hardware in a machine
2424 is properly shutdown, so do not be surprised if this code does not
2425 initially work for you. As of this writing the exact hardware
2426 interface is strongly in flux, so no good recommendation can be

2435 a specially reserved region and then later executed after
2436 a crash by kdump/kexec. The crash dump kernel must be compiled
2437 to a memory address not used by the main kernel or firmware using
2438 PHYSICAL_START.

2456 help
2457 This kernel feature is useful for number crunching applications
2458 that may need to compute untrusted bytecode during their
2459 execution. By using pipes or other transports made available to
2460 the process as file descriptors supporting the read/write
2461 syscalls, it's possible to isolate those applications in
2462 their own address space using seccomp. Once seccomp is
2463 enabled via /proc/<pid>/seccomp, it cannot be disabled
2464 and the task is only allowed to execute a few safe syscalls
2465 defined by each seccomp mode.

2472 help
2473 When this is enabled, the kernel will support use of 64-bit floating
2474 point registers with binaries using the O32 ABI along with the
2475 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2476 32-bit MIPS systems this support is at the cost of increasing the
2477 size and complexity of the compiled FPU emulator. Thus if you are
2478 running a MIPS32 system and know that none of your userland binaries
2479 will require 64-bit floating point, you may wish to reduce the size
2480 of your kernel & potentially improve FP emulation performance by
2481 saying N here.
2482
2483 Although binutils currently supports use of this flag the details
2484 concerning its effect upon the O32 ABI in userland are still being
2485 worked on. In order to avoid userland becoming dependant upon current
2486 behaviour before the details have been finalised, this option should
2487 be considered experimental and only enabled by those working upon
2488 said details.
