A couple of fixes for the AMD IOMMU driver have piled up: * Some fixes for the reworked IO page-table which caused memory leaks or did not allow to downgrade mappings under some conditions. * Locking fixes to fix a couple of possible races around accessing 'struct protection_domain'. The races got introduced when the dma-ops path became lock-less in the fast-path. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl2PrpoACgkQK/BELZcB GuNo6A/9EpxNUllqaPLvGYJYPN1ye2kx9QOCYZW6vo+at10X9ywf69IqYtjP9cSe x5uWUy0BFjBhqHvMvQ+9m6begFsue/+csUZDmeP+KvBHwNxUOxFS/fb4P0WlmmNF /zzsjQbt+r1FRIdYodH2CvBJKyuxNxou0W1aARvs9iggoXVG5Es+WG9+kwnixBE+ WB1gpuX0zKWlu31z2+i+JrVtdjMqoupfR/T40C4OsMD3NjfNi0bkCqmnqJ3CpNh9 RWPmNlnd29imPhMYQonZcUFD6Ru4NOUCfEFCjHEK/nk9kSHMYjgkKFgOzvA8h1xG Nkzd0dRw39UMNYzKDGHHaE/xXRJV+kOFxZBcABnxfx2r+9EgXBD36AUOsfpeOdVi 9ab75ok7Ly+tkCgdK7sEeuDD0HJiZkUYT7BqMTdBOt64BK/GtRvepF1Zv15hG6Xn imlAfyE4q+avTAJkrXeIu6IgdvF4XvorsIdeF5dKjCBTdTkj8DLXq/gejAo0g1NO shOz9E2lde1IdeT+U580nZy9JmkKDFjyeG4QkwSz7Oln/gHIFQS1K8A4i30kGiok vMsJzBidtUuqRWupwymtobCAggZE86O2XLOwnxolarJAFOqg5V2j7fSyL+XxXUDC r85Ve/jtAhMho5594X72CumoNzzr0bDyCcGerzvT0wBRXcKLIsw= =xajX -----END PGP SIGNATURE----- Merge tag 'iommu-fixes-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu fixes from Joerg Roedel: "A couple of fixes for the AMD IOMMU driver have piled up: - Some fixes for the reworked IO page-table which caused memory leaks or did not allow to downgrade mappings under some conditions. - Locking fixes to fix a couple of possible races around accessing 'struct protection_domain'.
