[PATCH RFC] vhost: basic device IOTLB support
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 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
