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