Does anybody know if there's any reason why generic fixmap.h uses negative offsets? It complicates things with no obvious benefit if you e.g. try to align virtual address in the fixmap region with physical page color (that's why I've switched xtensa to positive fixmap addressing in v3.17). -- Thanks. -- Max -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
