certain VT-d IOMMUs may not work in shared page table mode

ISSUE DESCRIPTION For efficiency reasons, address translation control structures page tables may and, on suitable hardware, by default will be shared between CPUs, for second-level translation EPT, and IOMMUs. These page tables are presently set up to always be 4 levels deep. However, an IOMMU ma...
