[PATCH]: make prototype of printk available

[PATCH]: make prototype of printk available

[Juan Quintela]

Hi
        this complained about printk being undefined.
        Once there, put a tag to the printk.

Later, Juan.

 Why is the default log level incorrect here?

This is a printk that's executed if a user program is just trying to
execute the right code, so a user could flood syslog that way.  Imho the
printk call should go away?

The problem (not here in general), is that if printk's use the default
log level, then you as a user has no way to raise/lower the default
log level (i.e. the messages that you want to printk or not).

 Indeed -- that's a report of a non-fatal exception.  If unhandled, user
will get output from the default signal handler.  And if diagnostics is
needed in the emulator, Dprintk or a similar solution may be used.

 Well, the default level is KERN_WARNING and can be changed using sysctl. 
Otherwise it's handled identically to explicitly tagged messages -- you
may control direct console output with the same sysctl. 

 Obviously there are printks that beg for an explicit tag.
