Subject: [PATCH] iommu/amd: use new invalidate_range mmu-notifier
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Make use of the new invalidate_range mmu_notifier call-back and remove the
old logic of assigning an empty page-table between invalidate_range_start
and invalidate_range_end.
