I have around 130 patches for warnings that I'm submitting at the moment, but there are a couple of really tricky ones that I don't currently have a good plan for: - in some configurations, you end up without any boards selected, hitting an #error in the final link - ARMv3 support in gcc is rather broken and causes internal compiler errors among other things - the old ELF format (OABI) doesn't work in some cases - GCOV_PROFILE_ALL causes problems that need to be debugged - XIP_KERNEL sometimes causes kallsyms to fail - not all platforms implement the complete clk API, if they don't use CONFIG_COMMON_CLK (I have patch for that we can probably merge) - CONFIG_PHYS_OFFSET needs to be entered manually to be a number in 'make config' - same for DEBUG_LL Arnd From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mout.kundenserver.de ([212.227.17.10]:63750 "EHLO mout.kundenserver.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751233AbcA0Jov (ORCPT ); Wed, 27 Jan 2016 04:44:51 -0500 From: Arnd Bergmann Subject: Re: [linux-review:James-Hogan/kbuild-Remove-stale-asm-generic-wrappers/20160119-183642] d979f99e9cc14e2667e9b6e268db695977e4197a BUILD DONE Date: Wed, 27 Jan 2016 10:44:01 +0100 Message-ID: <3596300.IYfzmako0c@wuerfel> In-Reply-To: <20160127093018.GA21190@wfg-t540p.sh.intel.com> References: <569e1dbb.MgLv8OaZwklOxxtU%fengguang.wu@intel.com> <1947556.38OyJnvGS5@wuerfel> <20160127093018.GA21190@wfg-t540p.sh.intel.com> MIME-Version: 1.0 Content-Transfer-Encoding: 7Bit Content-Type: text/plain; charset="us-ascii" Sender: linux-arch-owner@vger.kernel.org List-ID: To: Fengguang Wu Cc: James Hogan , linux-mips@linux-mips.org, linux-arch@vger.kernel.org, linux-kbuild@vger.kernel.org, Florian Fainelli , Paul Burton , Ralf Baechle , Heinrich Schuchardt , linux-kernel@vger.kernel.org, Michal Marek , linux-arm-kernel@lists.infradead.org Message-ID: <20160127094401.Am5L7KzuNalvUARQIWEsU44uOsUf772OA0RZD93ch8w@z> On Wednesday 27 January 2016 17:30:18 Fengguang Wu wrote: > > Looks good, I'm just unsure about "multi_v8_defconfig", this does not > > exist.
