Message-Id: <1291677875-30493-7-git-send-email-konrad.wilk@oracle.com> Date: Mon, 6 Dec 2010 18:24:18 -0500 From: Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> To: airlied@...ux.ie, tglx@...utronix.de, hpa@...or.com, airlied@...hat.com, linux-kernel@...r.kernel.org, konrad@...nel.org Cc: Jeremy Fitzhardinge <jeremy@...p.org>, Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> Subject: [PATCH 06/23] agp/ali: Use the dma_addr instead of page_to_phys for m1541_[alloc|destroy]_page. The dma_addr contains the same value as page_to_phys(page). That is until the PCI API is enabled at which point the dma_addr will contain the true DMA (bus) address - which on baremetal will in all likehood be the same as page_to_phys(page). But under Xen, it might be different.
