603 will also generate a notice in the boot log before disabling
604 itself if the CPU in question is not capable of rate rounding.

623 help
624 kexec is a system call that implements the ability to shutdown your
625 current kernel, and to start another kernel. It is like a reboot
626 but it is independent of the system firmware. And like a reboot
627 you can start any kernel with it, not just Linux.
628
629 The name comes from the similarity to the exec system call.
630
631 It is an ongoing process to be certain the hardware in a machine
632 is properly shutdown, so do not be surprised if this code does not
633 initially work for you. It may help to enable device hotplugging
634 support. As of this writing the exact hardware interface is
635 strongly in flux, so no good recommendation can be made.

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
670 mode.

679 This enables support for systems with more than one CPU. If you have
680 a system with only one CPU, like most personal computers, say N. If
681 you have a system with more than one CPU, say Y.
682
683 If you say N here, the kernel will run on single and multiprocessor
684 machines, but will use only one CPU of a multiprocessor machine. If
685 you say Y here, the kernel will run on many, but not all,
686 singleprocessor machines. On a singleprocessor machine, the kernel
687 will run faster if you say N here.
688
689 People using multiprocessor machines who say Y here should also say
690 Y to "Enhanced Real Time Clock Support", below.

739 atomic operations using a software implementation of load-locked/

741 LLSC, this should be more efficient than the other alternative of
742 disabling interrupts around the atomic sequence.
