Well, we might be able to build generic kernels one day. So you need to judge whether some bits of code are needed/useful if run on your processor in a generic configuration (use PRId then) or are specific to a configuration dedicated to your processor (use a config option then). There are places in the existing code that violate the rule but the reasons are mostly historical and they will hopefully get cleaned up sooner or later (I have a few of them on my to-do list, too). Thus please don't be much too influenced by old code. -- + Maciej W.
