From 1d804535c37cb669334781afdbc2987284621623 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Fri, 13 Dec 2013 19:26:13 -0800 Subject: [PATCH] ion: don't use phys_to_page or __phys_to_pfn phys_to_page and __phys_to_pfn don't exist on all platforms. Use a combination of pfn_to_page, PFN_DOWN, page_to_pfn, and virt_to_page to get the same results.
