211 If you configure the kernel to include many drivers built-in instead
212 as modules, the kernel executable may become too big, so that the
213 linker will not be able to resolve some long branches and fails to link
214 your vmlinux kernel. In that case enabling this option will help you

358 help
359 kexec is a system call that implements the ability to shutdown your
360 current kernel, and to start another kernel. It is like a reboot
361 but it is independent of the system firmware. And like a reboot
362 you can start any kernel with it, not just Linux.
363
364 It is an ongoing process to be certain the hardware in a machine
365 shutdown, so do not be surprised if this code does not
366 initially work for you.

373 This enables the kexec_file_load() System call. This is
374 file based and takes file descriptors as system call argument
375 for kernel and initramfs as opposed to list of segments as
376 accepted by previous system call.
