+### Changed
+ - Quarantining of passed-through PCI devices no longer defaults to directing
I/O to a scratch
+ page, matching original post-XSA-302 behavior (albeit the change was also
backported, first
+ appearing in 4.12.2 and 4.11.4). Prior (4.13...4.15-like) behavior can be
arranged for
+ either by enabling the IOMMU_QUARANTINE_SCRATCH_PAGE setting at build
(configuration) time
+ or by passing "iommu=quarantine=scratch-page" on the hypervisor command
line.
