this type of checking in the v3 code since ages, but v2 will happily compile any code with bogus printk format strings and/or parameters. This can cause real bugs and at least needs to emit a warning, if not an error. Go with a warning for now since most of the flagged format strings are wrong but harmless in a 32-bit x86 environment.
