Geoff, another question about kexec-tools part is, can the kexec-tools code
been written in kernel? We have the infrastructure for kexec_file_load.

In the future if we have to support loading a signed kernel then we still
need to do that, but we may have to support both the kexec-tools and the
in kernel loader for compatibility purpose. It will be hard to maintain.

Thanks
