[PATCH 2/2] vhost: disentangle vring endianness stuff from the core code
...vhost_init_used(vq);
> if (r)
> goto err_used;
This is in fact a bug in existing code: if vhost_init_used
fails, it preferably should not have side-effects.
It's best to update it last thing.

[PATCH 0/2] vhost: cross-endian code cleanup
This series is a respin of the following patch:
http://patchwork.ozlabs.org/patch/565921/
Patch 1 is preliminary work: it gives better names to the helpers that are
involved in cross-endian support.
Patch 2 is actually a v2 of the original patch. All devices now call a
helper in the generic code, which DTRT according to vq->private_data, as
suggested by Michael.
