IOMMU Fixes for Linux v5.13-rc3
Including:
- Important fix for the AMD IOMMU driver in the recently added
page-specific invalidation code to fix a calculation.
- Fix a NULL-ptr dereference in the AMD IOMMU driver when a
device switches domain types.
- Fixes for the Intel VT-d driver to check for allocation
failure and do correct cleanup.
- Another fix for Intel VT-d to not allow supervisor page
requests from devices when using second level page
translation.
- Add a MODULE_DEVICE_TABLE to the VIRTIO IOMMU driver
iommu/vt-d: Fix sysfs leak in alloc_iommu()
iommu_device_sysfs_add() is called before, so is has to be cleaned on subsequent
errors.
