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

111	help
112	  Say Y to export the bootinfo used to boot the kernel in a
113	  "bootinfo" file in procfs.  This is useful with kexec.
