Hi All,
I have been trying to boot the latest Xen code on Seattle (while I am
getting the patch ready to be sent out), and I ran into the following
issue.

I have not tracked down to a particular commit ID. But do you guys see
anything suspicious with the error message?
The elf_init thing is suspicious, it suggests Xen hasn't properly
figured out the type of your kernel image. Is it a regular bare arm64
Image (from arch/arm64/boot/Image)? You can't boot the vmlinux from the
top level directly (AFAIK).
Actually, I bisect it down to this commit ID causing it to break:
commit 73b9bdfd2adab8ed0cea91d3e4470b0d1bf76591

xen/arm: Add virtual GICv3 support
CORRECTION: Wrong commit ID here.
It's the commit bc183a0235e092bb0dd3cea97fc4ea55c490101e
xen/arm: Add support for GIC v3
Sorry for confusion.
