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

From: James Bottomley <JBottomley@Parallels.com>
commit 68ed7e1c3d236e9e1e60ed6cae22f2c1c4ba2952 upstream.
This is a partial revert of 2f2dafe (serial: serial_core.c: printk replacement) which gets us booting again. The real problem seems to be the _emit path in early boot. However, until we can root cause it, we need at least to get boot working.
