No, we need to not just blindly copy what arm did for historic reasons
unless we have a very good reason of our own.

In addition to not having a real need for any of this in a new setup,
it also is duplicated by the retain_initrd parameter which is
implemented in generic code - and for that the commit message at least
has a rationale related to kexec:
