Hi,  I noticed another pr for Fedora kexec-tools:
https://src.fedoraproject.org/rpms/kexec-tools/pull-request/24

It is bad to take it as Fedora only,   I would suggest posting all the
refreshed patches together here again for review.

If no enough reviewers can review them my another suggestion is to
drop the kexec_load support code for the time being, and only enable
the kexec_file_load support code in kexec-tools, and I assume below
kernel commit make the kexec_file_load kernel piece of work done.
Then it will be easier to review and make something working at least.
