Hi Takao Indoh,
Your update for the patchset works fine. Thanks.

 Joerg,
I am working following  your directions:

1.  If the VT-d driver finds the IOMMU enabled, it reuses its root entry
table, and do NOT disable-enable iommu. Other data will be copied.

2. When a device driver issues the first dma_map command for a
device, we assign a new and empty page-table, thus removing all
mappings from the old kernel for the device.

Please let me know if I get something wrong.

Thanks
Zhenhua
