636 kexec is a system call that implements the ability to shutdown your
637 current kernel, and to start another kernel. It is like a reboot
638 but it is independent of the system firmware. And like a reboot
639 you can start any kernel with it, not just Linux.
641 The name comes from the similarity to the exec system call.
643 It is an ongoing process to be certain the hardware in a machine
644 is properly shutdown, so do not be surprised if this code does not
645 initially work for you. As of this writing the exact hardware
646 interface is strongly in flux, so no good recommendation can be

654 This should be normally only set in special crash dump kernels
655 which are loaded in the main kernel with kexec-tools into
656 a specially reserved region and then later executed after
657 a crash by kdump/kexec. The crash dump kernel must be compiled

674 This gives the physical address where the kernel is loaded
675 and is ordinarily the same as MEMORY_START.
677 Different values are primarily used in the case of kexec on panic
678 where the fail safe kernel needs to run at a different address
679 than the panic-ed kernel.
682 bool "Enable seccomp to safely compute untrusted bytecode"
685 This kernel feature is useful for number crunching applications
686 that may need to compute untrusted bytecode during their
687 execution. By using pipes or other transports made available to
688 the process as file descriptors supporting the read/write
689 syscalls, it's possible to isolate those applications in
690 their own address space using seccomp. Once seccomp is
691 enabled via prctl, it cannot be disabled and the task is only
692 allowed to execute a few safe syscalls defined by each seccomp
697 config CC_STACKPROTECTOR
698 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
701 This option turns on the -fstack-protector GCC feature. This
702 feature puts, at the beginning of functions, a canary value on
703 the stack just before the return address, and validates
704 the value just before actually returning. Stack based buffer
705 overflows (that need to overwrite this return address) now also
706 overwrite the canary, which gets detected and the attack is then
707 neutralized via a kernel panic.
709 This feature requires gcc version 4.2 or above.
712 bool "Symmetric multi-processing support"
713 depends on SYS_SUPPORTS_SMP
714 select USE_GENERIC_SMP_HELPERS
716 This enables support for systems with more than one CPU. If you have
717 a system with only one CPU, like most personal computers, say N. If
718 you have a system with more than one CPU, say Y.
720 If you say N here, the kernel will run on single and multiprocessor
721 machines, but will use only one CPU of a multiprocessor machine. If
722 you say Y here, the kernel will run on many, but not all,
723 singleprocessor machines. On a singleprocessor machine, the kernel
724 will run faster if you say N here.
726 People using multiprocessor machines who say Y here should also say
727 Y to "Enhanced Real Time Clock Support", below.
729 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
730 available at <http://www.tldp.org/docs.html#howto>.
732 If you don't know what to do here, say N.
735 int "Maximum number of CPUs (2-32)"
738 default "4" if CPU_SUBTYPE_SHX3
741 This allows you to specify the maximum number of CPUs which this
742 kernel will support. The maximum supported value is 32 and the
743 minimum value which makes sense is 2.
745 This is purely to save memory - each supported CPU adds
746 approximately eight kilobytes to the kernel image.

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

765 For additional information, design information can be found
766 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
768 This should only be disabled for special cases where alternate
769 atomicity implementations exist.
772 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
773 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
775 Enabling this option will allow the kernel to implement some
776 atomic operations using a software implementation of load-locked/
777 store-conditional (LLSC). On machines which do not have hardware
778 LLSC, this should be more efficient than the other alternative of
779 disabling interrupts around the atomic sequence.
