557 kexec is a system call that implements the ability to shutdown your
558 current kernel, and to start another kernel. It is like a reboot
559 but it is independent of the system firmware. And like a reboot
560 you can start any kernel with it, not just Linux.
561
562 The name comes from the similarity to the exec system call.
563
564 It is an ongoing process to be certain the hardware in a machine
565 is properly shutdown, so do not be surprised if this code does not
566 initially work for you. As of this writing the exact hardware
567 interface is strongly in flux, so no good recommendation can be

663 Enabling this option will allow the kernel to implement some
664 atomic operations using a software implementation of load-locked/
665 store-conditional (LLSC). On machines which do not have hardware
666 LLSC, this should be more efficient than the other alternative of
667 disabling interrupts around the atomic sequence.
