[PATCH 0/2] vhot-net: Use kvm_memslots instead of vhost_memory to translate GPA to HVA
From: Hongyong Zang <zanghongyong at huawei.com>
Vhost-net uses its own vhost_memory, which results from user space (qemu) info,
to translate GPA to HVA. Since kernel's kvm structure already maintains the
address relationship in its member *kvm_memslots*, these patches use kernel's
kvm_memslots directly without the need of initialization and maintenance of
vhost_memory....

[RFC PATCH V2 0/2] 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 (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
