Why 4.8? That too is a totally unsupported kernel version. Anyway, randomly pulling in a driver from a newer by many years, if not almost a decade old (2.6.32 was released in 2009), is a very difficult task, and usually almost impossible to go that far back. That is not how Linux is developed or meant to be worked with at all. You are _really_ on your own here, only do this if you _really_ know what you are doing. Even then, I would not recommend you do this, as you are guaranteeing to create a monstrosity that only you can support, for forever, on your own. good luck! greg k-h From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org X-Spam-Level: X-Spam-Status: No, score=-2.3 required=3.0 tests=HEADER_FROM_DIFFERENT_DOMAINS, MAILING_LIST_MULTI,SPF_PASS,USER_AGENT_MUTT autolearn=ham autolearn_force=no version=3.4.0 Received: from mail.kernel.org (mail.kernel.org [198.145.29.99]) by smtp.lore.kernel.org (Postfix) with ESMTP id 3BAFBC433F5 for ; Sun, 2 Sep 2018 15:13:07 +0000 (UTC) Received: from vger.kernel.org (vger.kernel.org [209.132.180.67]) by mail.kernel.org (Postfix) with ESMTP id D7AA620841 for ; Sun, 2 Sep 2018 15:13:06 +0000 (UTC) DMARC-Filter: OpenDMARC Filter v1.3.2 mail.kernel.org D7AA620841 Authentication-Results: mail.kernel.org; dmarc=none (p=none dis=none) header.from=linuxfoundation.org Authentication-Results: mail.kernel.org; spf=none smtp.mailfrom=linux-kernel-owner@vger.kernel.org Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1727100AbeIBTSU (ORCPT ); Sun, 2 Sep 2018 15:18:20 -0400 Received: from mail.linuxfoundation.org ([140.211.169.12]:40148 "EHLO mail.linuxfoundation.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1726195AbeIBTST (ORCPT ); Sun, 2 Sep 2018 15:18:19 -0400 Received: from localhost (ip-213-127-74-90.ip.prioritytelecom.net [213.127.74.90]) by mail.linuxfoundation.org (Postfix) with ESMTPSA id 096B7CA8; Sun, 2 Sep 2018 15:02:11 +0000 (UTC) Date: Sun, 2 Sep 2018 17:02:09 +0200 From: Greg Kroah-Hartman To: Nitin Gupta Cc: ldv-project@linuxtesting.org, devel@driverdev.osuosl.org, Pavel Zemlyanoy , linux-kernel@vger.kernel.org, linux-erofs@lists.ozlabs.org Subject: Re: SKylake Edac support in linux 2.6.32.696 kernel build Message-ID: <20180902150209.GA25883@kroah.com> References: <20180831161450.GB26043@kroah.com> <20180831194727.GA8631@kroah.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: User-Agent: Mutt/1.10.1 (2018-07-13) Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org On Sun, Sep 02, 2018 at 03:45:01PM +0530, Nitin Gupta wrote: > Hi Greg > > i am working on some project which is having huge changes and working > on kernel-2.6.32-131.696 > it will be very difficult to back port them into 4.8 .
