Subject: [PATCH 1/2] Documentation/memory-barriers.txt: cross-reference "tools/memory-model/"

Recent efforts led to the specification of a memory consistency model
for the Linux kernel [1], which "can (roughly speaking) be thought of
as an automated version of memory-barriers.txt" and which is (in turn)
"accompanied by extensive documentation on its use and its design".

Make sure that the (occasional) reader of memory-barriers.txt will be
aware of these developments.
