From 27e8b237944af967e0a808580278d432cb028455 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Thu, 2 Dec 2010 10:24:13 -0500 Subject: ttm: Expand (*populate) to support an array of DMA addresses. We pass in the array of ttm pages to be populated in the GART/MM of the card (or AGP). Patch titled: "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set." uses the DMA API to make those pages have a proper DMA addresses (in the situation where page_to_phys or virt_to_phys do not give use the DMA (bus) address). Since we are using the DMA API on those pages, we should pass in the DMA address to this function so it can save it in its proper fields (later patches use it).

This makes the accounting when using 'debug_dma_dump_mappings()' and CONFIG_DMA_API_DEBUG=y be assigned to the correct device instead of 'fallback'. No functional change - just cosmetic.
