Thanks, I verified the test kernel fixes the bug.

To do so, I ran the specjbb2005 benchmark in a pinned guest with base page backing and compared that to a pinned guest with 2MB hugepage backing. On the stock 4.15.0-10 kernel, the 2MB backing throughput was w/in run variance (1.5%). With the fixed test kernel (#11~lp1752236), the 2MB backing provided 8% guest throughput improvement as expected for this workload.
