See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-pci@vger.kernel.org Hi all, this series tries to clean up the swiotlb initialization, including that of swiotlb-xen. To get there is also removes the x86 iommu table infrastructure that massively obsfucates the initialization path.
