From 2ae9f2fa3f770c734e713f9a0a4c40bcf2373ab6 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 31 Jul 2013 19:21:25 +0100 Subject: [PATCH] iommu/arm-smmu: Remove broken big-endian check The bottom word of the pgd should always be written to the low half of the TTBR, so we don't need to swap anything for big-endian.
