The problem is that, address_space_get_iotlb_entry() shares a lot with address_space_translate(). This patch tries to abstract the shared elements.
Originally, this work is derived from discussion from VT-d passthrough series discussions [1]. But for sure we can just see this series as a standalone cleanup. So I posted it separately here. Smoke tests are done with general VM boots, IOs, especially with vhost dmar configurations. I believe with current series I can throw away the old patch [1], which may be good. But before that, please kindly review. Thanks.
