It seems either your purgatory code was not built correctly,
or the kexec-tools relocator didn't do the correct thing.

Please post the output from your gcc with the --version option and
the command line used to compile purgatory/purgatory.c.

As I mentioned before, these patches only add kexec re-boot support.  kdump
has not been ported to arm64 yet.
