From: Andy Lutomirski <l...@amacapital.net>

commit 53b884ac3745353de220d92ef792515c3ae692f0 upstream.

This commit in Linux 3.6:

    commit c767a54ba0657e52e6edaa97cbe0b0a8bf1c1655
    Author: Joe Perches <j...@perches.com>
    Date:   Mon May 21 19:50:07 2012 -0700

        x86/debug: Add KERN_<LEVEL> to bare printks, convert printks to 
pr_<level>

caused warn_bad_vsyscall to output garbage in the middle of the
line.  Revert the bad part of it.

The printk in question isn't actually bare; the level is "%s".

The bug this fixes is purely cosmetic; backports are optional.
