After discussion with the NSLU2 people, it was agreed we should just get
on with it. I've updated the zaurus kernels (linux-rp) and kexec-tools
itself. The NSLU2 kernels will follow. Anyone else using ARM kexec needs
to ensure their kernel uses the new syscall number 347.

OE users should ensure their kernels and kexec-tools versions match.
