insufficient cache write-back under VT-d

ISSUE DESCRIPTION When page tables are shared between IOMMU and CPU, changes to them require flushing of both TLBs. Furthermore, IOMMUs may be non-coherent, and hence prior to flushing IOMMU TLBs CPU cached also needs writing back to memory after changes were made. Such writing back of cached dat...
