I think there is a virt_to_bus() macro and its inverse.
Which is deprecate and not to be used by any new code. Use Documentation/DMA-mapping.txt instead.
If you meant virt_to_phys(), this does not work on arbitrary kernel virtual addresses either only direct mapped ones (ie. kmalloc() or get_free_page() data). - 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/
