    x86: Remove spurious printk level from segfault message · a1a08d1c
    Roland Dreier authored
    Since commit 5fd29d6c ("printk: clean up handling of log-levels
    and newlines"), the kernel logs segfaults like:
    
        <6>gnome-power-man[24509]: segfault at 20 ip 00007f9d4950465a sp 00007fffbb50fc70 error 4 in libgobject-2.0.so.0.2103.0[7f9d494f7000+45000]
    
    with the extra "<6>" being KERN_INFO.  This happens because the
    printk in show_signal_msg() started with KERN_CONT and then
    used "%s" to pass in the real level; and KERN_CONT is no longer
    an empty string, and printk only pays attention to the level at
    the very beginning of the format string.
    
    Therefore, remove the KERN_CONT from this printk, since it is
    now actively causing problems (and never really made any
    sense).
