Subject: [PATCH v3 0/7] vhost: support for cross endian guests

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
