Bug description:
== SRU Justification ==
IBM is requesting commit 76fa4975f3ed in powerpc as a security fix.
This commit Fixes: 121f80ba68f1. Commit 76fa4975f3ed also requires
mainline commit 1463edca6734 as a prereq.
Both these commits have already been cc'd to upstream stable, but they
have not landed in Bionic as of yet.
== Fixes ==
1463edca6734 ("vfio/spapr: Use IOMMU pageshift rather than pagesize")
76fa4975f3ed ("KVM: PPC: Check if IOMMU page is contained in the pinned
physical page")
== Regression Potential ==
Low. These commits have also been sent to upstream stable, so have had
additional upstream review.
== Test Case ==
A test kernel was built with these patches and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
