-Subject: [PATCH 12/67] amd-vi: fix IVMD memory type checks
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The current code that parses the IVMD blocks is relaxed with regard to the
-restriction that such unity regions should always fall into memory ranges
-marked as reserved in the memory map.
-
-However the type checks for the IVMD addresses are inverted, and as a result
-IVMD ranges falling into RAM areas are accepted.  Note that having such ranges
-in the first place is a firmware bug, as IVMD should always fall into reserved
-ranges.
-
-Fixes: ed6c77ebf0c1 ('AMD/IOMMU: check / convert IVMD ranges for being / to be reserved')
