Subject: [PATCH 3.2 077/102] init/Kconfig: Hide printk log config if
 CONFIG_PRINTK=n

3.2.64-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Josh Triplett <josh@...htriplett.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.

Acked-by: Randy Dunlap <rdunlap@...radead.org>
[bwh: Backported to 3.2: drop change to CONFIG_LOG_CPU_MAX_BUF_SHIFT]
