You've changed tabs to spaces.

Instead of changing each and every seclvl_printk() call to add
__FUNCTION__, why not do this:

+static void __seclvl_printk(int verb, const char *fmt, ...)
...

#define seclvl_printk(verb, fmt, arg...) \
	__seclvl_printk(verb, __FUNCTION__ ": " fmt, arg)

It requires that the fmt be a string literal, but it saves a lot of code
duplication.  I'm sure there are some more examples of this around as
well.
