From: Zhen Lei Date: Fri, 26 Jun 2015 08:32:59 +0000 (+0100) Subject: iommu/arm-smmu: Fix the values of ARM64_TCR_{I,O}RGN0_SHIFT X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5d58c6207c300340151931ad9c2cdea2d1685dc4;p=linux-beck.git iommu/arm-smmu: Fix the values of ARM64_TCR_{I,O}RGN0_SHIFT The arm64 CPU architecture defines TCR[8:11] as holding the inner and outer memory attributes for TTBR0. This patch fixes the ARM SMMUv3 driver to pack these bits into the context descriptor, rather than picking up the TTBR1 attributes as it currently does.
