-From: <security@xenproject.org>
-Subject: vtd: prune (and rename) cache flush functions
-
-Rename __iommu_flush_cache to iommu_sync_cache and remove
-iommu_flush_cache_page. Also remove the iommu_flush_cache_entry
-wrapper and just use iommu_sync_cache instead. Note the _entry suffix
-was meaningless as the wrapper was already taking a size parameter in
-bytes. While there also constify the addr parameter.
-
-No functional change intended.
-
-This is part of XSA-321.
