I don't think this was meant to go to the list.

It's a fixup for the patch I posted in my RFC series at
https://lists.xenproject.org/archives/html/xen-devel/2020-01/msg02690.html

The original testing was just hard-coding addresses and using a
'normal' kexec load, and we were only testing KEXEC_TYPE_LIVE_UPDATE
for the actual kexec_exec.

Once Varad had implemented the automatic placement support in kexec
userspace tools, we spotted that the load operation wasn't working for
KEXEC_TYPE_LIVE_UPDATE, hence this fixup.

I merged it into the appropriate patch in my tree some time last week.
