From 0b8698ab5847cbe25775083659f00c658a8161c9 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 9 Jan 2009 18:32:09 +0000 Subject: swiotlb: range_needs_mapping should take a physical address. The swiotlb_arch_range_needs_mapping() hook should take a physical address rather than a virtual address in order to support highmem pages.
