sadly there are multiple mappings, both in theory and practice. Especially the _np / _p functions specifically work on only the mapping you specify.
For this to work we would need to somehow make a "mark all mappings NP, but please only do the kernel ones" kind of thing. The semantics of that are... lets say messy at best. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
