Well, it's a half-assed one. And some systems have a real one. But the real problem is that virt_to_bus doesn't exist at all on architectures like ppc64, and this patch touches files like generic.c and backend.c that aren't PC-specific. So you effectively break agp support for them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
