It would involve comparing the virtual address with the kmap and atomic kmap regions, performing a pagetable walk, extracting the pageframe. If the page is not in a kmap area generate the pageframe directly. Make that work on all architectures. Very yuk. If practical this API should have been defined in terms of (page/offset/len) and it should have kmapped the pages itself. I guess it's too late for that. - 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/ | ||||||||||||
