I have reasons for wanting kexec_load, even if we have kexec_file_load.
For example, being able to test modified DTBs during development, and
being able to kexec to non-Linux OSs.

I don't think we should drop kexec_load, as kexec_file_load is designed
such that it cannot be used for these purposes, while kexec_load is more
general.

I appreciate that we will need kexec_file_load for Secure Boot, and it
would be perfectly fine for your kdump userspace to require and always
use kexec_file_load.

Thanks,
Mark.
