Hi: This series tries to fix various issues of vhost: - Patch 1 adds a missing write barrier between used idx updating and logging. - Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries. - Patch 4-7 fixes the diry page logging when device IOTLB is enabled. We should done through GPA instead of GIOVA, this was done through intorudce HVA->GPA reverse mapping and convert HVA to GPA during logging dirty pages. Please consider them for -stable. Thanks Changes from V1: - silent compiler warning for 32b...
