Yes from my part ;). It looks more correct than calling io_remap_page_range under an #ifdef CONFIG_XEN. One thing I don't know is why for example sparc isn't already doing that (like XEN is already doing that with your patch). Sparc and XEN are the only two archs where io_remap_page_range isn't an alias to remap_pfn/page_range. It's much nicer if we use io_remap_page_range in the same places for both sparc and XEN. Though to get the final answer we should ask the sparc folks. - 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/
