Hello,

While testing some things out, I found a possible bug in Xen.  Xen would
successfully run when loaded (from u-boot) at some addresses but not
others.  I didn't observe this issue in 4.11 stable, so I did a bisect
and found that:
commit f60658c6ae47e74792e6cc48ea2effac8bb52826

    xen/arm: Stop relocating Xen

was what was causing it to fail when it was loaded to that certain
address.

I've attached the logs from a build from staging (about a week or so
ago) with both a passing and failing address.
