I feel kexec was ready to merge nine months ago.  Users have only sent
private e-mails like yourself, so there has been no public inquiries,
and so, the arm64 maintainers think kexec is not of interest to users.

Does kexec on ARM64 support ACPI?  In some of our initial tests, it 
appears that the kexec'd kernel won't boot because it's expecting a 
device tree, and we don't have one.

ACPI support has just been merged and is still experimental. You
should be able to boot your system by passing a DT blob at the
initial boot that matches your hardware. Can you try if that
makes kexec work?
