Two series: - Reorganize how the hardware page table objects are managed, particularly their destruction flow. Increase the selftest test coverage in this area by creating a more complete mock iommu driver. This is preparation to add a replace operation for HWPT binding, which is done but waiting for the VFIO parts to complete so there is a user. - Split the iommufd support for "access" to make it two step - allocate an access then link it to an IOAS. Update VFIO and have VFIO always create an access even for the VFIO mdevs that never do DMA. This is also preperation for the replace VFIO series that will allow replace to work on access types as well. Three minor fixes: - Sykzaller found the selftest code didn't check for overflow when processing user VAs - smatch noted a .data item should have been static - Add a selftest that reproduces a syzkaller bug for batch carry already fixed in rc -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZEfgkQAKCRCFwuHvBreF YRw7AQD5BhiTzdTMlMPAasihb2ZITYs3MyiZrxICZuZf3CksLAD9FcO3aYPq01ge 7yHF+LeWHYq1dR6x7YTvcbc3apFFIgA= =0j6E -----END PGP SIGNATURE----- Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd updates from Jason Gunthorpe: "Two series: - Reorganize how the hardware page table objects are managed, particularly their destruction flow.
