102	help
103	  kexec is a system call that implements the ability to shutdown your
104	  current kernel, and to start another kernel.  It is like a reboot
105	  but it is independent of the system firmware.   And like a reboot
106	  you can start any kernel with it, not just Linux.
107
108	  The name comes from the similarity to the exec system call.
109
110	  It is an ongoing process to be certain the hardware in a machine
111	  is properly shutdown, so do not be surprised if this code does not
112	  initially work for you.  As of this writing the exact hardware
113	  interface is strongly in flux, so no good recommendation can be
114	  made.

121	  "bootinfo" file in procfs.  This is useful with kexec.
