This version contains little functional changes, mostly comment-wise and patch squashings. I squashed the last 4 patches since they are solving the same problem, meanwhile the old patch 9 itself might brought some problem if without patch 12 so I just squashed them all. I re-wrote the commit message for that patch (and it simplifies me to write the SECURITY part since all those four patches are solving the single problem). Reviewers can go to previous version 3 and have a look at patches 9-12 since the contents are totally the same (and I suppose that one might be easier for reviewers). V3: http://lists.gnu.org/archive/html/qemu-devel/2018-05/msg04009.html I made bold to have Jintack's Reported-by and Tested-by for the last big patch already, after I did some smoke test for this new version. v4: - rename: notifiers_list to vtd_as_with_notifiers, vtd_as_notify_mappings to vtd_as_has_map_notifier [Eric] - tune the comments in misc patches [Eric] - add missing places to take iommu lock [Eric] - for each patch: cc stable, add "SECURITY IMPLICATION" at the beginning of commit where necessary - merge patch 9-12 Please review. Thanks.
