iommu/amd: Allow to upgrade page-size Before this patch the iommu_map_page() function failed when it tried to map a huge-page where smaller mappings existed before. With this change the page-table pages of the old mappings are teared down, so that the huge-page can be mapped. Signed-off-by: Joerg Roedel <jroedel@suse.de>
