From: Jeremy Fitzhardinge Subject: [PATCH 0 of 9] swiotlb: use phys_addr_t for pages Date: Mon, 22 Dec 2008 10:26:02 -0800 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Ingo Molnar Cc: linux-kernel@vger.kernel.org, Xen-devel , the arch/x86 maintainers , Ian Campbell , Becky Bruce , FUJITA Tomonori List-Id: xen-devel@lists.xenproject.org Hi all, Here's a work in progress series whcih does a partial revert of the previous swiotlb changes, and does a partial replacement with Becky Bruce's series. The most important difference is Becky's use of phys_addr_t rather than page+offset to represent arbitrary pages. This turns out to be simpler. I didn't replicate the map_single_page changes, since I'm not exactly sure of ppc's requirements here, and it seemed like something that could be easily added. Quick testing showed no problems, but I haven't had the chance to do anything extensive. I've made some small changes to Becky's patches to make them apply, but I've separated any functional changes into separate patches with appropriate authorship. J
