I looked at adding support for permanent mappings but it was going to take more time than I had. Also on ARM, we have to deal with kmap's needs as well. Working that out was going to take more time than I had. I think getting the patch in now to support early_ioremap is the way to go. Adding support for permanent mappings can be done later with the early console support for which it is needed. -- 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/
