I tested the patch and it seems to work. A brew build for test kernel is here: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=11695090

I ran the kdump test suite today on RHEL 7.3 Snapshot 3 and it did not hang on the HP Moonshots.

1. disk-dump

2. nfs-dump
   https://beaker.engineering.redhat.com/recipes/3055684#tasks

Moving to Verified.
