From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Helgaas Subject: [PATCH 2/6] PCI: alpha: use generic INTx swizzle from PCI core Date: Tue, 16 Dec 2008 21:37:00 -0700 Message-ID: <20081217043700.8372.19362.stgit@bob.kio> References: <20081217043443.8372.28890.stgit@bob.kio> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from g1t0027.austin.hp.com ([15.216.28.34]:12514 "EHLO g1t0027.austin.hp.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751687AbYLQEhA (ORCPT ); Tue, 16 Dec 2008 23:37:00 -0500 In-Reply-To: <20081217043443.8372.28890.stgit@bob.kio> Sender: linux-arch-owner@vger.kernel.org List-ID: To: Jesse Barnes Cc: linux-pci@vger.kernel.org, linux-arch@vger.kernel.org, Ivan Kokshaysky , Russell King , Ralf Baechle , Paul Mundt , Thomas Gleixner , Ingo Molnar , hpa@zytor.com Use the generic pci_common_swizzle() instead of arch-specific code. Note that pci_common_swizzle() loops based on dev->bus->self, not dev->bus->parent as the alpha common_swizzle() did. I think they are equivalent for this purpose.
