From: Joerg Roedel Date: Wed, 2 Sep 2009 14:52:23 +0000 (+0200) Subject: x86/amd-iommu: Remove bus_addr check in iommu_map_page X-Git-Tag: upstream/snapshot3+hdmi~17695^2^2^2~4 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bad1cac28a707c69301a4d0612da9ccbecd51953;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git x86/amd-iommu: Remove bus_addr check in iommu_map_page The driver now supports full 64 bit device address spaces. So this check is not longer required.
