Subject: [SERIAL] Prefix serial printks with KERN_INFO and pre-format
X-Git-Tag: v2.6.14-rc1~775^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=30b7a3bc133c5b4a723163be35157ed709fca91c;p=linux-2.6

[SERIAL] Prefix serial printks with KERN_INFO and pre-format

Pre-format the IO part of the ttyS printks, and prefix them with
KERN_INFO to avoid bootsplash corruption.
