- Fix off by one error in intel_vgpu_write_fence() (Dan)
- Fix potential Spectre v1 (Gustavo)
- Fix workload free in vgpu release (Henry)
- Fix cleanup sequence in intel_gvt_clean_device (Henry)
- dmabuf mutex init place fix (Henry)
- possible memory leak in intel_vgpu_ioctl() err path (Yi)
- return error on cmd access check failure (Yan)
