From mboxrd@z Thu Jan 1 00:00:00 1970 From: tim.bird@am.sony.com (Tim Bird) Date: Tue, 18 Oct 2011 16:27:45 -0700 Subject: [PATCH 0/3] ARM 4Kstacks: introduction Message-ID: <4E9E0B71.9020708@am.sony.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org I'm about to submit a set of patches (really pretty small) to add 4K stack support to ARM (defaulted to 'N'). This has been kicking around in my Sony tree for a few years, and it's about time to mainline it. The first patch is the actual 4KSTACKS patch. See subsequent patches for tools to help with stack reduction to avoid the problems that apparently led to the removal of this feature on x86. This set includes: 0001-Add-support-for-4K-kernel-stacks-to-ARM.patch 0002-Add-static-kernel-function-stack-size-analyzer-for-ARM.patch 0003-Decrease-poll-and-select-stack-usage-when-using-4K-stacks.patch ============================= Tim Bird Architecture Group Chair, CE Workgroup of the Linux Foundation Senior Staff Engineer, Sony Network Entertainment ============================= From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1752073Ab1JRX3Y (ORCPT ); Tue, 18 Oct 2011 19:29:24 -0400 Received: from va3ehsobe006.messaging.microsoft.com ([216.32.180.16]:14838 "EHLO VA3EHSOBE007.bigfish.com" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1751468Ab1JRX3W (ORCPT ); Tue, 18 Oct 2011 19:29:22 -0400 X-SpamScore: 0 X-BigFish: VPS0(zzzz1202hzzz2fh668h839h) X-Forefront-Antispam-Report: CIP:160.33.98.74;KIP:(null);UIP:(null);IPVD:NLI;H:mail7.fw-bc.sony.com;RD:mail7.fw-bc.sony.com;EFVD:NLI X-FB-SS: 13, Message-ID: <4E9E0B71.9020708@am.sony.com> Date: Tue, 18 Oct 2011 16:27:45 -0700 From: Tim Bird User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.12) Gecko/20100907 Fedora/3.0.7-1.fc12 Thunderbird/3.0.7 MIME-Version: 1.0 To: Russell King , "linux-arm-kernel@lists.infradead.org" , Arnd Bergmann , Andi Kleen , Thomas Gleixner , linux kernel Subject: [PATCH 0/3] ARM 4Kstacks: introduction Content-Type: text/plain; charset="ISO-8859-1" Content-Transfer-Encoding: 7bit X-OriginatorOrg: am.sony.com Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I'm about to submit a set of patches (really pretty small) to add 4K stack support to ARM (defaulted to 'N').
