[PATCH 3.4 73/91] init/Kconfig: Hide printk log config if CONFIG_PRINTK=n

[lizf]

From: Josh Triplett <josh@xxxxxxxxxxxxxxxx>

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

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


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.

Signed-off-by: Josh Triplett <josh@xxxxxxxxxxxxxxxx>

[lizf: Backported to 3.4:
 - drop the change to CONFIG_LOG_CPU_MAX_BUF_SHIFT as it doesn't exist in 3.4]
