virt inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4WK5B
CVE: NA

------------------------------

The iommu_domain may contain more than one DMA range which can
be dirty log tracked separately, so it's hard to track the dirty
log status of iommu_domain. The upper layer (e.g. vfio) should
make sure it's doing right thing.

Fixes: bbf3b39e (iommu: Introduce dirty log tracking framework)
