Hi,
This patchset allows vhost to be used with legacy virtio when guest and host
have a different endianness.
Patches 1-6 remain the same as the previous post. Patch 7 was heavily changed
according to MST's comments.

Greg Kurz (7):
virtio: introduce virtio_is_little_endian() helper
tun: add tun_is_little_endian() helper
macvtap: introduce macvtap_is_little_endian() helper
vringh: introduce vringh_is_little_endian() helper
vhost: introduce vhost_is_little_endian() helper
virtio: add explicit big-endian support to memory accessors
vhost: feature to set the vring endianness

tun/macvtap patch.
