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

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