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

115	help
116	  Say Y to export the bootinfo used to boot the kernel in a
117	  "bootinfo" file in procfs.  This is useful with kexec.
