Hmm this doesn't look like an improvement to me.
What does it mean to disable big endian? Make it little endian?
Existing reset seems to make sense.

[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.
