Subject: [PATCH memory-model 6/7] docs/memory-barriers.txt: Remove left-over references to "CACHE COHERENCY"

From: Akira Yokosawa <akiyks@...il.com>

Commit 8ca924aeb4f2 ("Documentation/barriers: Remove references to
[smp_]read_barrier_depends()") removed the entire section of "CACHE
COHERENCY", without getting rid of its traces.

Remove them.
