Kexec is a system call which linux uses to load and execute another
kernel. Kexec has to be work differently under xen, because it's
loading into xen virtual memory not physical memory; but this is
supported by current linux kernels. Plan 9 would also need some
changes to be able to be loaded by kexec (under xen or otherwise);
I forget the details.
