297 kexec is a system call that implements the ability to shutdown your

301
1f1332f7 302 The name comes from the similarity to the exec system call.

304 It is an ongoing process to be certain the hardware in a machine
305 is properly shutdown, so do not be surprised if this code does not
306 initially work for you. It may help to enable device hotplugging
307 support. As of this writing the exact hardware interface is
308 strongly in flux, so no good recommendation can be made.

561 Find out whether your system includes a PCI bus. PCI is the name of
562 a bus system, i.e. the way the CPU talks to the other stuff inside
563 your box. If you say Y here, the kernel will include drivers and
564 infrastructure code to support PCI bus devices.

668 This builds a kernel image that is capable of running at the

672 One use is for the kexec on panic case where the recovery kernel
673 must live at a different physical address than the primary
674 kernel.
675
676 Note: If CONFIG_RELOCATABLE=y, then the kernel runs from the address
677 it has been loaded at and the compile time physical addresses
678 CONFIG_PHYSICAL_START is ignored. However CONFIG_PHYSICAL_START
679 setting can still be useful to bootwrappers that need to know the
