This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 19ced623db2fe91604d69f7d86b03144c5107739 ]
The hash buffer is really HASH_BLOCK_SIZE bytes, someone
must have thought that memmove takes n*u32 words by mistake.
Tests work as good/bad as before after this patch.
