From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Walmsley Subject: [PATCH 2/2] OMAP2420 IO mapping: move IVA mapping virtual address out of vmalloc space Date: Thu, 03 Dec 2009 01:15:59 -0700 Message-ID: <20091203081558.1004.57172.stgit@localhost.localdomain> References: <20091203081337.1004.51309.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from utopia.booyaka.com ([72.9.107.138]:60923 "EHLO utopia.booyaka.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751471AbZLCIQt (ORCPT ); Thu, 3 Dec 2009 03:16:49 -0500 In-Reply-To: <20091203081337.1004.51309.stgit@localhost.localdomain> Sender: linux-omap-owner@vger.kernel.org List-Id: linux-omap@vger.kernel.org To: linux-omap@vger.kernel.org Cc: Tony Lindgren , Santosh Shilimkar Commit 10db25fea4c11661070b97832b8cc3d2af495092 causes the following kernel messages during N800 boot (and presumably all other 2420 boards): [ 0.000000] BUG: mapping for 0x58000000 at 0xe0000000 overlaps vmalloc space [ 0.000000] BUG: mapping for 0x59000000 at 0xe1000000 overlaps vmalloc space [ 0.000000] BUG: mapping for 0x5a000000 at 0xe2000000 overlaps vmalloc space Fix by remapping the IVA memory areas somewhere outside vmalloc space.
