x86_64/vsyscall: Fix warn_bad_vsyscall log output
commit 53b884ac3745353de220d92ef792515c3ae692f0 upstream. This commit in Linux 3.6: commit c767a54ba0657e52e6edaa97cbe0b0a8bf1c1655 Author: Joe Perches <joe@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.
