For the guest\nwithout assigned device, the memory type of guest memory would always been the\nsame as host(WB); but for the assigned device, some part of memory may be used\nas DMA and then set to uncacheable memory type(UC/WC), which would be a conflict of\nhost memory type then be a potential issue.\n\nSnooping control can guarantee the cache correctness of memory go through the\nDMA engine of VT-d.\n\n[avi: fix build on ia64]\n\nSigned-off-by: Sheng Yang \u003csheng@linux.intel.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n",
