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

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

From: Josh Triplett <josh@joshtriplett.org>

commit 361e9dfbaae84b0b246ed18d1ab7c82a1a41b53e upstream.

The buffers sized by CONFIG_LOG_BUF_SHIFT and
CONFIG_LOG_CPU_MAX_BUF_SHIFT do not exist if CONFIG_PRINTK=n, so don't
ask about their size at all.

[ kamal: backport to 3.13-stable: only LOG_BUF_SHIFT ]
