[PATCH] reduce syslog clutter

[Tilman Schmidt]

The current versions of the err() / info() / warn() syslog macros
insert __FILE__ at the beginning of the message, which expands to
the complete path name of the source file within the kernel tree.

With the following patch, when used in a module, they'll insert the
module name instead, which is significantly shorter and also tends to
be more useful to users trying to make sense of a particular message.

The patch also adds macros for the KERN_NOTICE severity level which
was so far uncatered for.
