This patch tries to implement an device IOTLB for vhost. This could be used with for co-operation with userspace(qemu) implementation of iommu for a secure DMA environment (DMAR) in guest. The idea is simple. When vhost meets an IOTLB miss, it will request the assistance of userspace to do the translation, this is done through: - Fill the translation request in a preset userspace address (This
