613 kexec is a system call that implements the ability to shutdown your
614 current kernel, and to start another kernel. It is like a reboot
615 but it is independent of the system firmware. And like a reboot
616 you can start any kernel with it, not just Linux.
618 The name comes from the similarity to the exec system call.
620 It is an ongoing process to be certain the hardware in a machine
621 is properly shutdown, so do not be surprised if this code does not
622 initially work for you. As of this writing the exact hardware
623 interface is strongly in flux, so no good recommendation can be

631 This should be normally only set in special crash dump kernels
632 which are loaded in the main kernel with kexec-tools into
633 a specially reserved region and then later executed after
634 a crash by kdump/kexec. The crash dump kernel must be compiled
635 to a memory address not used by the main kernel using

651 This gives the physical address where the kernel is loaded
652 and is ordinarily the same as MEMORY_START.
654 Different values are primarily used in the case of kexec on panic
655 where the fail safe kernel needs to run at a different address
656 than the panic-ed kernel.
659 bool "Enable seccomp to safely compute untrusted bytecode"
662 This kernel feature is useful for number crunching applications
663 that may need to compute untrusted bytecode during their
664 execution. By using pipes or other transports made available to
665 the process as file descriptors supporting the read/write
666 syscalls, it's possible to isolate those applications in
667 their own address space using seccomp. Once seccomp is
668 enabled via prctl, it cannot be disabled and the task is only
669 allowed to execute a few safe syscalls defined by each seccomp
675 bool "Symmetric multi-processing support"
676 depends on SYS_SUPPORTS_SMP
678 This enables support for systems with more than one CPU. If you have
679 a system with only one CPU, say N. If you have a system with more
682 If you say N here, the kernel will run on uni- and multiprocessor
683 machines, but will use only one CPU of a multiprocessor machine. If
684 you say Y here, the kernel will run on many, but not all,
685 uniprocessor machines. On a uniprocessor machine, the kernel
686 will run faster if you say N here.
688 People using multiprocessor machines who say Y here should also say
689 Y to "Enhanced Real Time Clock Support", below.
691 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
692 available at <http://www.tldp.org/docs.html#howto>.
694 If you don't know what to do here, say N.

703 This allows you to specify the maximum number of CPUs which this
704 kernel will support. The maximum supported value is 32 and the
705 minimum value which makes sense is 2.
707 This is purely to save memory - each supported CPU adds
708 approximately eight kilobytes to the kernel image.

715 can be controlled through /sys/devices/system/cpu.

723 This enables support for gUSA (general UserSpace Atomicity).
724 This is the default implementation for both UP and non-ll/sc
725 CPUs, and is used by the libc, amongst others.
727 For additional information, design information can be found
728 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
730 This should only be disabled for special cases where alternate
731 atomicity implementations exist.
734 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
735 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
737 Enabling this option will allow the kernel to implement some
738 atomic operations using a software implementation of load-locked/
739 store-conditional (LLSC). On machines which do not have hardware
740 LLSC, this should be more efficient than the other alternative of
741 disabling interrupts around the atomic sequence.
