---8<------------------------------------------------------------
From: Oded Gabbay <oded.gabbay@xxxxxxxxx>
commit 687f4b98d1f4e27508f7ad4bcce787c1ba58b289 upstream.
This patch fixes the VCE ring test when running on Big-Endian machines.
Every write to the ring needs to be translated to little-endian.
