[PATCH v2 0/3] vhost: cross-endian code cleanup
This series is a new tentative to have cleaner cross-endian code.
Patches 1/3 is new: it fixes a side-effect in case vhost_init_used() fails.
Patch 2/3 comes from v1: it renames cross-endian helpers
Patch 3/3 is new: it simply renames vhost_init_used() as suggested by Michael.

[PATCH V2 0/3] basic device IOTLB support for vhost_net
This patch tries to implement an device IOTLB for vhost. This could be
used with for co-operation with userspace IOMMU implementation (qemu)
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:
- when there's a IOTLB miss, it will notify userspace through
