Subject: [ 73/73] nouveau: Fix alignment requirements on src and dst addresses

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maarten Lankhorst <maarten.lankhorst@...onical.com>

commit ce806a30470bcd846d148bf39d46de3ad7748228 upstream.

Linear copy works by adding the offset to the buffer address,
which may end up not being 16-byte aligned.

Some tests I've written for prime_pcopy show that the engine
allows this correctly, so the restriction on lowest 4 bits of
address can be lifted safely.

The comments added were by envyas, I think because I used
a newer version.
