kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
- but it is indepedent of the system firmware. And like a reboot

you can start any kernel with it, not just Linux.
The name comes from the similiarity to the exec system call.

- This provides basic support for the National Semiconductor SCx200

+ This provides basic support for National Semiconductor's
+ (now AMD's) Geode processors. The driver probes for the
+ PCI-IDs of several on-chip devices, so its a good dependency
+ for other scx200_* drivers.
- If you don't know what to do here, say N.

- This support is also available as a module. If compiled as a
